What is SAP Transaction WE19?

SAP Transaction WE19 is a transaction code used to process IDocs in SAP. IDocs are electronic data interchange (EDI) documents that facilitate the exchange of data between different systems. With WE19, you can simulate the processing of IDocs, allowing you to test and troubleshoot any issues before executing them in a live environment. This transaction is particularly useful for SAP consultants and developers working with integration scenarios involving external systems.

Step 1: Accessing SAP Transaction WE19

To access WE19, follow these steps:

  1. Login to your SAP system using your user ID and password.
  2. Launch the SAP Easy Access Menu.
  3. Expand the \\\”Tools\\\” folder.
  4. Select \\\”IDoc Interface / Application Link Enabling (ALE)\\\”.
  5. Choose \\\”Data Transfer\\\” and click on \\\”Test\\\”.
  6. In the next screen, select \\\”Test IDoc Processing\\\”.
  7. Click on \\\”Execute\\\” or press F8 to proceed to the WE19 transaction.

Step 2: Understanding WE19 Transaction Screen

Once you have accessed WE19, you will see the transaction screen, which consists of various fields and tabs. Let’s explore each of them:

  • IDoc Search Criteria: This section allows you to search for specific IDocs based on various criteria such as IDoc number, partner number, or message type.
  • Processing Options: Here, you can define the processing options for the selected IDoc, including simulation mode, error handling, and test run settings.
  • Processing Steps: This tab displays the individual processing steps of the IDoc, including inbound and outbound processing, data conversion, and error handling.
  • IDoc Data: In this section, you can view and edit the data contained within the selected IDoc, including segments and fields.
  • Partner Profiles: The partner profiles tab shows the partner profiles associated with the IDoc, providing information about the sender and receiver systems.
  • Status Tracking: Here, you can track the status of the IDoc, including its current processing status and any errors encountered during processing.

Step 3: Simulating IDoc Processing with WE19

To simulate IDoc processing using WE19, follow these steps:

  1. Start by entering the search criteria for the IDoc you want to process. This can be the IDoc number, partner number, or message type.
  2. Click on the \\\”Execute\\\” button to search for the IDoc.
  3. Once the IDoc is displayed, navigate to the \\\”Processing Options\\\” tab and select the desired simulation mode (e.g., test run).
  4. Configure any additional processing options as required, such as error handling and test run settings.
  5. Switch to the \\\”Processing Steps\\\” tab to view the individual processing steps of the IDoc.
  6. Click on the desired processing step and choose \\\”Process Inbound\\\” or \\\”Process Outbound\\\” to simulate the processing of the IDoc.
  7. If necessary, make any changes to the IDoc data in the \\\”IDoc Data\\\” section by editing the segments and fields.
  8. Once you have completed the simulation, click on the \\\”Save\\\” button to save the changes made to the IDoc data.

Congratulations! You have successfully simulated IDoc processing using SAP transaction WE19.

Step 4: Additional Functionality in WE19

While simulating IDoc processing is the primary functionality of WE19, there are additional features that can further enhance your testing and troubleshooting activities. Here are some notable functionalities:

  • Display IDocs: Use WE19 to display existing IDocs by entering the IDoc number or other relevant criteria. This allows you to review the content and structure of IDocs for analysis and troubleshooting purposes.
  • Change IDocs: WE19 also enables you to modify existing IDocs. You can edit the segments and fields within an IDoc, allowing you to test different scenarios and evaluate the impact on downstream processes.
  • Resend IDocs: In case of processing errors or failed IDocs, WE19 allows you to resend the IDocs for reprocessing. This feature helps in retriggering the integration process and resolving any issues.
  • Error Handling: WE19 provides detailed error information for IDocs, allowing you to identify and resolve any errors encountered during processing. You can view error messages, log files, and perform error analysis to rectify the issues.


In this tutorial, we have provided you with a step-by-step guide on using SAP transaction WE19 for testing and processing IDocs.
