• What is the cause and solution for SAP error message R11156 - Passed partner GUID &1 and found partner GUID &2 do not match ?

  The SAP error message R11156 indicates a mismatch between two partner GUIDs (Globally Unique Identifiers) during a process that involves partner data, such as in the context of IDoc processing, EDI transactions, or other integration scenarios. This error typically arises when the system expects a specific partner GUID but finds a different one instead.
  Cause:
  
  
  Data Mismatch: The most common cause is that the data being processed references a partner that does not match the expected GUID. This can happen if:
  
  The partner data has been changed or updated incorrectly.
  There are inconsistencies in the partner profiles or master data.
  The wrong partner is being referenced in the transaction or IDoc.
  
  
  
  Configuration Issues: Incorrect configuration in partner profiles or settings in the relevant modules (like EDI, ALE, etc.) can lead to this error.
  
  
  IDoc Issues: If the IDoc being processed has been altered or is not correctly formatted, it may lead to GUID mismatches.
  
  
  Solution:
  
  
  Verify Partner Data: Check the partner profiles in the SAP system to ensure that the GUIDs are correctly configured. You can do this by:
  
  Navigating to the relevant transaction (e.g., WE20 for partner profiles).
  Ensuring that the partner settings are correct and that the GUIDs match what is expected.
  
  
  
  Check IDoc Data: If the error occurs during IDoc processing, examine the IDoc for any discrepancies. You can use transaction WE02 or WE05 to view the IDoc details and check the partner information.
  
  
  Reprocess the IDoc: If the IDoc is found to be incorrect, you may need to correct the data and reprocess the IDoc.
  
  
  Review Configuration: Ensure that the configuration settings for the relevant modules (like EDI or ALE) are correctly set up. This includes checking the logical systems, RFC destinations, and any other related settings.
  
  
  Consult Documentation: If the issue persists, refer to SAP documentation or support notes related to the specific error message for additional troubleshooting steps.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as WE20 (Partner Profiles), WE02/WE05 (IDoc Monitoring), and others that may help in diagnosing the issue.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common problems.
