Shap rfecv Explaining XGBoost predictions with SHAP value: a comprehensive guide to interpreting decision tree-based models From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Since I don't know much about SQnn, I won't be able to answer all of your questions. The DIALOG restriction for processing a dialog step applies for this (standard: 300 seconds, system profile parameter (rdisp/max_wprun_time) also for these RFC calls. To show how this works in practice, we’ll start with a contrived In this study, we used the Boruta-shap and RFC-RFECV algorithms to automatically identify and extract characteristic miRNAs highly associated with lung cancer, thereby establishing an accurate classifier for the diagnosis of lung cancer with characteristic miRNAs. The certified RFC function module /DABEXP/RFC_SAPCONNECTOR is required to connect a SAP-system to the dab SAP-Extraction Solutions. 54 and SAP-RFC 1. Surprisingly, even if i remove RFC destination in datastore and put a dummy value, i'm still able to extract data. 50 Programming Guide. 0C onwards), RFC server programs can be started before, register at this Gateway and then wait for RFC call Solved: hi folks, I have a little problen to call RFC by Vb. Async example below shows basic principles and you can check --> BAPI is used only when it is available for the particular transaction like Delivery Sales order. pyplot as plt from sklearn. But for a few days we try to call many fields from a table. Since SAP version 7. Solution Outline The fit method has a parameter features to keep, at each step, the method will make sure to not remove the features to always keep. Now we are performing local client copy within the DEV system from client 300 to 200. At the time of the problem there is a performance issue on ServerB that cause high CPU utilization and a slow down in processing of RFC calls. SAP Support Backbone Update / Upcoming changes in SAP Service and Support backbone interfaces / How the SAP Support Backbone update affects ABAP systems, SAP Solution Manager systems, and Focused Run for SAP Solution Manager systems +++ ATTENTION +++ Support of RFC- About this page This is a preview of a SAP Knowledge Base Article. I have installed 'Wamp' server with PHP 5. The problem has been rectified by giving the adapter specific identifiers(R/3 System ID and Client) forIDOC and RFC Adapter in R/3 business system Concept. You can use a receiver Remote Function Call (RFC) adapter to connect SAP systems and non SAP systems. feature_selection import RFECV from sklearn. It supports binary classification, regression models and hyperparameter optimization at every feature elimination step. As there were some new changes done on RFC i have re-imported the new structure into XI and activated. SHAP values offer a principled game-theoretic approach to feature importance scoring and, as such, can be combined with both RFE and Boruta. May be client is having size o The SAP Java Connector (SAP JCo) is a development library that enables a Java application to communicate with on-premise SAP systems via SAP's RFC protocol. I am using old version of PHP because I could not find much of help for PHP version 7. The SAP JCo supports both communication directions: inbound Remote Function Calls (Java calls ABAP) as well as I want to do a connection with SAP-RFC using PHP. RFCs facilitate remote function execution in a seamless and efficient manner. model_selection import train_test_split from sklearn. --> INTERFACE : These are used for tranfering the data from SAP to non-SAP and vice-versa. Click more to access the full version on SAP for Me (Login required). But, my client asked to use Eclipse and CDS to achieve this functionality. The RFECV visualizer plots the number of features in the model along with their cross-validated test score and variability and visualizes the selected number of features. There are configurations necessary both within Babelway and within the target SAP system, but we have set it up so that the process is as simple as possible for all parties involved. These features are then compared with RFECV-selected features when it is integrated. Based on tool support in ABAP development tools for Eclipse (ADT), you can generate an ABAP proxy for calling one or more remote-enabled function modules (RFMs) using the SRVC. Scikit-learn provides RFECV class to implement RFECV method to find the most important features in a given dataset. In design time, you must import the interface of a remote-enabled function module from the business system into the ESR for the corresponding Software Component Version (SWCV) in the same way that you import IDoc types. Available Filter Options. You want to share your content then reach us via email: info@sapcodes. " How can I know which particular features are selected with RFECV?If I do X_rfecv_train=selector. If you want to ShapRFECV vs sklearn RFECV¶ In this section we will compare the performance of the model trained on the features selected using the probatus ShapRFECV and the sklearn RFECV. To learn how to create a Service Consumption Model with ADT, see Creating Service Consumption Model. Objective: This study aimed to identify a set of serum miRNAs as potential biomarkers for lung cancer diagnosis using algorithmic approaches. Now I want this RFC Destination in QAS & PRD. We showed an application where we used grid-search and Recursive Feature Elimination but random-search and Boruta are other Further information about the SHAP-RFECV algorithm and its applications can be found on the Probatus webpage 2. How to get SHAP values for each class on a multiclass classification problem in Python. e. Select the gateway service (<gateway_service>) (usually sapgw and system number). Since SAP GUI for Windows is a 32bit program, which is also true for its Active libraries like LogonControl, it Event trace (transaction SWEL) showing RFC Status: System overloaded, repeat immediately by batch All dialog work processes are used by WF-BATCH Image/data in this KBA is from SAP internal systems, sample data, or demo systems. Shap RFECV makes it possible to remove from features to prune a set of features to keep always. Dear community, Many of you still rely heavily on the legacy SAP interface RFC. Initially I found all sorts of approaches - writing a custom BSP, developing my own WebDynPro page, post the data into some database and import it from there later Hi All, I use RFC_READ_TABLE in order to read some table values from another SAP system. Any resemblance to real data is purely c To mark this page as a favorite, you need to log in with your SAP ID. We are waiting to finish this copy from last 48 hours. 8, Apache 2. . In a nutshell, the SHAP value of a feature corresponding to a specific model prediction represents the contribution to the deviation of the specific decision made from the baseline decision, I got a requirement to use RFC function module to get the data third party system. Pardon me, but if I remember right SAP tolds us since years that the ActiveX controls are only for compatibility reasons available, not for further development and production. Selecting optimal features is important part of data preparation in machine learning. When the users trying to use Repository Comparison Version they got the message: " User does not hav We use RFC_READ_TABLE from VB and it works perfect. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. Visit SAP Support Portal's SAP Notes and KBA Search. This dashboard shows statistics for RFC calls. Hello, is it possible to call a sap rfc report (transactioncode ZRFUH) from a sap fiori application? And if it is possible, how can I do it? Thanks in advance Jay SAP Automation RFC and BAPI Interfaces (BC-FES-AIT) One of the methods for integrating an external PC application to R/3 is by using the RFC interfaces of R/3, also called the RFC channel.

Is there an official document from SAP on that (stating the limit or the scalability conditions). ShapRFECV - Recursive Feature Elimination using SHAP importance¶ Recursive Feature Elimination allows you to efficiently reduce the number of features in your dataset, without When building a machine learning model, selecting a suitable subset of features may significantly improve the performance of the final solution. com . How to query which Function Module has been called by a history RFC with user and time stamp information "Image/data in this KBA is from SAP internal systems, sample data, or demo systems. Recursive feature elimination with cross-validation to select features. Are You Feeling Overwhelmed Learning Data Science? Sep 19, 2024. It is used for the purpose of exchanging business documents - such as sales orders, invoices, or master data records - between modules in an SAP system, between different SAP systems, or between SAP and non-SAP systems. transform(X_train), I get a numpy array, but I don't know feature names. See Usage and API, also SAP NWRFC SDK 7. In order to call remote enabled ABAP function module, we need to create a node-rfc client instance with valid logon credentials, connect to SAP ABAP NetWeaver system and then invoke a remote enabled ABAP function module from nodejs. Example. 4. Via the RFC API, an external system can communicate as client or server with the SAP system. They have different pros and cons, and usually feature selection is best achieved by also involving common sense and trying models with different features. 2 million members across 205 countries. 6C. Graphical abstract. After an attack vector was published in the talk "SAP Gateway to Heaven" from Mathieu Geli and Issue Description Compare RFECV with ShapRFECV in an experiment in a jupyter notebook Make a page in docs presenting this experiment Code snippets There are some ready to use code snippets: from probatus. Hi, I am working on JDBC to RFC scenario. Use of SAP RFCs for ABAP data extraction (except for SAP-internal applications) is not permitted by SAP. T Solved: Hi, We have a thirdparty tax component Vertex integrated with our ECC. I checked th In ABAP Development Tools (ADT), in Project Explorer, open your ABAP Environment instance. for ex: if we are using VB application,where in that we want to connect to SAP and retireve the data,and then change and update the data in SAP for that purpose we can use that. sklearn. In the project, create a new ABAP package. Hi, in case you are using for the RFC connection logongroups , then you need to do a couple of additional steps: 1) Set up VPN from CCv2 to customer network, add remote systems and NAT rules for all required message servers and (!) application servers. The following example shows how the client program can work with two SAProuters and a message server or Further information about the SHAP-RFECV algorithm and its applications can be found on the Probatus webpage 2. HI, I have a Proxy-to-RFC scenario. I don't know, sorry.

Everyone Knows SAP, Everyone Uses SAP, Everyone Uses RFC, No One Knows RFC: From RFC to RCE 16 Years Later Hagg, Fabian Emanuel SEC Consult Vulnerability Lab - SEC Consult, an Eviden business Here a step by step guide to expose the RFC-enabled function module RFC_READ_TABLE as WebService and how to use it via JavaScript: Start transaction code SE80 and create a new Enterprise Service. There are two important configuration options when using RFE: the choice The SHAP-RFECV ensures to avoid bias in feature selection, and its use shows to reduce problems of fitting to noise [25]. Symptom 1: The parallel RFC processing of an external RFC desination in SM58 is very slow even the setting which decribed in the note 400330 has already finished. RFC already has a higher performance than other communication technologies of the ABAP server, which is why RFC is the ABAP server’s technology for heavy-load-scenarios – such as, for example, a single transfer of a huge data load with a huge internal table or It is not possible to call any standard transaction remotely as most of them are legacy-like and doesn't return anything directly. Not all users are to have access to payslip etc, so that role is not assigned to everyone. In The study employs an Explainable Artificial Intelligence (XAI) framework called SHapley Additive exPlanations (SHAP) to derive the crucial features when RFECV is not integrated with the ML models. feature_selection. the total size of the DB is 150 GB. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. the technical requirements for RFC with SAP and external systems.

If you do not have an SAP ID, you can create one for free from the login page. Introduction: By leveraging RFC, organizations can enable robust data exchange and process integration across different SAP and non-SAP systems. Today, I see more customers of SAP that do have a license in place to access the database of their S/4HANA system. Contribute to airbus-seclab/powersap development by creating an account on GitHub. from sklearn. Improve this answer. The plot above presents the averaged CV Validation AUC of model performance for each round of the RFE process in both ShapRFECV and RFECV. It helps reduce the complexity of machine learning models, improve performance, mitigate overfitting, and decrease computation time. Articial Intelligence (XAI) framework called SHapley Additive exPlanations (SHAP) to derive the crucial features when RFECV is not integrated with the ML models. Just a couple of days ago I found myself confronted with a little problem. In this tutorial example, it is when you have an RFC Sender integration via SAP Process Orchestration, and after the migration to Cloud Integration, you want to switch this RFC Sender communication to the SOAP Sender protocol. I am curious as how is it working. The proxy class contains a specific method for each called RFM.

The use of Shapley values for ML interpretability was first introduced by Štrumbelj and Kononenko in 2010. So, if that external server change the IP address, do we have to re-register the program with rfcexec in our gateway again or SAP will update the IP address and details using the ho Seamlessly integrating and sharing data across various systems and processes is essential in today’s complex business landscape. Often Kerberos is disc RFC, or Remote Function Call, is a fundamental concept in SAP systems, used extensively for communication between SAP systems themselves Performance comparison on test data (image by the author) SUMMARY. I registered RFC Program ID in SAP and i am able to extract data in a regular dataflow. It is running too slow. I have searched the our community, someone use the following to solve the issue, but it co Hello Michael, I don't know Office 365 but in my opinion you give the right answer, it is not possible to use SAP ActiveX controls with x64 version of Office, like I described here. Is this the correct process for feature selection? This is ONE of the many ways of feature selection. This means, on OS level the call of a program is always waiting for an answer. see SAP Note 3337381: SAP NetWeaver RFC SDK 7. 2. Yes - set an external breakpoint right inside the function module and trace its execution while performing the RFC call. Can be downloaded from SAP Software Download Center of the SAP Support Portal, like The RFECV function provided by the SKlearn library facilitates this process. In order to compare them let's first Recursive feature elimination with cross-validation to select features. 0+2acd15650. For example, assume the training data we passed were split into 3 groups. The method was then popularized and extended by Lundberg et al. 0. rf_rec = RandomForestClassifier(n_jobs=-1, max_depth = 20, max_features = 0. This paper presents a novel feature selection framework, shap-select. To harness their full potential, these RFCs often need to be exposed as web services, providing a standa Select the gateway host (<gateway_host>) (IP address or host name). fit_compute ( X_train, y_train ) # Compare the CV SHAP helps when we perform feature selection with ranking-based algorithms. Read more in the User Guide. It allows you to serialize tRFC calls using a queue. Purpose. These features shap_elimination = ShapRFECV ( clf=clf, step=1, cv=10, scoring='roc_auc', n_jobs=3 ) shap_report = shap_elimination. RFC (Performance) For RFC Performance Monitoring, you can collect all RFC destinations in the managed system. The method uses a backward feature elimination based on the SHAP value of feature importance. I was asked to update data in an SAP system from a web page. Still, one of the pr The entries are delivered with the system. I have done the following steps: 1. Hello, I've noticed the following RFC calls during a period of heavy load in the system.

Scenario We will be using a RFC to get data that we need in our automation. datasets import load_breast_cancer from sklearn. Create a new ABAP class: Choose File > New > Other > ABAP Class. Introduction. RFE is popular because it is easy to configure and use and because it is effective at selecting those features (columns) in a training dataset that are more or most relevant in predicting the target variable. The number of features selected is tuned automatically by fitting an RFE selector on the different cross-validation splits Please see SAP note 1442028: SAP GUI for Windows - Support for Office 64bit editions. In this study, we used the Boruta-shap and RFC-RFECV algorithms to automatically identify and extract characteristic miRNAs highly associated with lung cancer, thereby establishing an accurate classifier for the diagnosis of lung cancer with characteristic miRNAs. Choose IMG Path: Financial accounting (New)>Financial accounting global settings (New)>Taxes on sales/purchases>Basic settings>External tax calculation>Define physical destination Reading directly from tables in your SAP ERP system has, in the past, always been impossible, not from a technical point of view, but due to licensing restrictions. The most practical way of retrieveing data from SAP to Excel is to find proper BAPI or remote-enabled FM, (including writing own Join the discussions or start your own on all things application development, including tools and APIs, programming models, and keeping your skills sharp. An RFC server program can be started by the currently running SAPGUI, by the currently running SAP application server or by an Gateway, as described in the above section. If so, the CSL uses this port. But I have no knowledge in RFC receiver adapter. This site is not affiliated with SAP SE. If there is no entry for SY R, it is Dear All: I have work out a Excel VBA macro to read RFC to read data from SAP Systems. Hi folks, could be possible include a RFECV in Boruta? Something similar to probatus https://github. Execute transaction code STMS. (2)Train model on "train" groups/splits. 9, min_samples_leaf = 2, min_samples_split = 0. Specify a unique program ID (<programm_id>), for example, “dalecheck”. I using this code: Public Sub New() '---- - 'Cria conexão com o SAP '---- - '--- Inicio Feature selection is an essential process in machine learning, especially when dealing with high-dimensional datasets. Search for additional results. We use Round Robin load balancing for all login groups. 1, n_estimators = 100, oob_score=True, It's due to the fact that your Office is in 64 bits version, and SAP GUI for Windows up to version 7. A python package for simultaneous Hyperparameters Tuning and Features Selection for Gradient Boosting Models. Recursive Feature Elimination, or RFE for short, is a popular feature selection algorithm. If no RFC port for system SYR was entered in the CSL_CCP table, the CSL uses the RFC port that was entered in the TBLSYSDEST database table. The number of features selected is tuned automatically by fitting an RFE selector on the different cross-validation splits You can directly compute RFECV using sklearn by building your estimator that computes feature importance, using any logic you want, when calling fit. 51. By default 64bit programs cannot load 32bit programs. Contribute to metalsimyaci/SapCo2 development by creating an account on GitHub. In this blog, we will explore the different types of RFC calls Although SHAP importance shows the effect of a given feature on the model output while disregarding the exactness of the prediction, our study, by comparing the highly contributing features in the without feature selection You can directly compute RFECV using sklearn by building your estimator that computes feature importance, using any logic you want, This logic can be customized using any estimator (both regressor or classifier) and any feature importance logic (like SHAP or similar) Share. The designed model is trained with all features initially and uses cross-validation (10-fold) to estimate each feature's SHAP importance value. In my world that often means customers connecting their third-party services to SAP backends (AS ABAP). how the RFC Interface functions. 1. The receiver adapter contains the technical information of the connection to the back-end system. But it doesen't About this page This is a preview of a SAP Knowledge Base Article. 0 and the release of SAP NetWeaver, Web services have become the standard for interfaces.

SOAP web services are one of the newest technologies for connecting SAP to different systems. just ask because I want to know if there is a fix for this so that we don't need to restart the service eve RFECV (Recursive Feature Elimination with Cross-Validation) performs recursive feature elimination with cross-validation loop to extract the optimal features. 26 to the so‐called SHAP SAP Connector for . The qRFC (queued Remote Function Call) is an extension of the tRFC. Instead of using the default variable importance, generated by gradient boosting, we select the Remote Function Call (RFC) is a powerful feature in SAP ABAP, enabling communication between SAP systems, as well as between SAP systems and external systems. My guess is that the basic cycle for RFECV is (1) split the data into n - in this example 3 - number of "splits" or "groups". Symptom 2: Connection test of External RFC destination in T-code:SM59 finished with high response time: L hi everyone, why we use "apply control record from payload ",in idoc recevier adapter?how many types of rfc's are there?

Using ABAP programming it is a cake walk for any ABAP developer. After an attack vector was published in the talk "SAP Gateway to Heaven" from Mathieu Geli and Powershell SAP assessment tool. Here’s why you should use ODP and SAP OData instead. This works fine in principle - it returns data converted to characters, which I can access via wa+offset(length). Thanks in advance. 2020-04-07 Cloud Improvements and Advantages of Fast Serialization in More Detail Higher Performance. In this post, we introduced shap-hypetune, as a helpful framework to carry out parameter tuning and optimal features searching for gradient boosting models. learn documentation. Babelway has created a specific gateway for establishing an RFC with an SAP system. As many of us are new to Eclipse and CDS views. The dab SAP-Extraction Solution Add-On is then instal Dear all, We have an RFC destination with a gateway registered program which belong to an external server/application. After doing R&D and found one RFC meets Web - Part II: How to build the proxy Welcome back to the second blog post where we look into building the REST2RFC proxy! It's a SAP Cloud SDK Java application running on SAP BTP Cloud Foundry runtime. 50 -- Patch Level 12 for a list of bug fixes and enhancements made with this patch release. ; Only the latest patch level is supported by SAP; The latest version is fully backwards compatible, from today S4, down to R/3 release 4. Changed in parameters like Host/server IP, SAPinsider is the largest and fastest-growing SAP membership group worldwide, with more than 1. Net5. Prerequisites: Basic Knowledge about RFC Basic knowledge about SAP Build Basic knowledge about SAP Process Automation. Introduction and BTP services used When I started with the project (which was inspired Everyone looking for SHAP for feature selection (and hyperparameters tuning), I suggest shap-hypetune. So far I m Because of internal security reasons the individual users are not having enough authorization to use transaction SREPO between two SAP systems (e. Does RFC mean the "RFC destination" or the RFC function module? I assume the interviewer asked for the first one because the latter one just means to call a function module remotely. Environment Local PC OS: Windows10 64-bit CF cli: 6. How can I move this or even it is In rare cases, access to transactions to perform mass loads or to affect changes to data with any significant volume are restricted for users--even for users who are responsible for maintaining Master Data. It helps us Any RFC client program can connect to an SAP System via SAProuter. One option is to use Excel to create an OLE connection to the SAPGUI interface to run scripts, but that option requires scripting to be turned on in the SAP system OS command execution using sapxpg As you may have read in part 1 of this series, starting a program on OS level is an interactive task. The number of features selected is tuned automatically by fitting an RFE selector on the different cross-validation splits Hi All, I am writing this blog to describe steps to build RFC connection from cloud to on-premise using SAP Cloud Connector. You may choose to manage your own preferences. For RFECV, the code returns a different number from 1-25 (not half of the number of features) It seems to me that when RFECV is being selected, the number of features is being picked only based on the KFCV scores - i. We want to import 38 fields from a table. It supports feature selection with RFE or Boruta and parameter tuning with Grid or Random Search. The Integration Service uses this connection to connect to SAP and make BAPI/RFC function calls to extract, transform, or load data. datasets import make_classification from sklearn. The announcement is multicast with the same scope as the session it is announcing, ensuring that the recipients of the announcement are within the scope of the session the announcement The SAP Remote Function Calls (RFC) adapter is both an input and output adapter. It provides SAP professionals with invaluable information, strategic guidance, and road-tested advice, through events, magazine articles, blogs, podcasts, interactive Q&As, benchmark reports and webinars. Note that RFC calls with CALL FUNCTION are processed in DIALOG work processes. the cross validation scores are over-riding RFE's successive pruning of features. g. 25 The authors showed how Shapley values can be used to fairly quantify the contribution of features in a ML model. Also for LGBM, In this section we will compare the performance of the model trained on the features selected using the probatus ShapRFECV and the sklearn RFECV. Access the transaction SE80 Starting an RFC server program. There are couple of ways to fetch data from any transaction but they are out of the scope of this question. After an attack vector was published in the talk "SAP Gateway to Heaven" from Mathieu Geli and This site is managed by Manish Shankar and Prasad . One or more SAProuters can be used (depending on your network architecture). Remember to consider this restriction when dividing up your data packets for parallel processing. For more information, see Set Up SAP BTP, ABAP Environment and create Your First Console Application. Results show that without RFECV the ML models achieve better classication accuracies on two datasets. To resolve the issue, we need to restart the service which connects to the ABAP system. However, creating RFCs is only half the battle. Net program. Securing a protocol such as SAP Remote Function Call (RFC) requires network layer protection. the functionality provided by RFC. aRFC work process utilization. Contribute to piersharding/RSAP development by creating an account on GitHub.
