• What is the cause and solution for SAP error message AD674 - Source message ID and target message ID must be different ?

  The SAP error message AD674, which states "Source message ID and target message ID must be different," typically occurs in the context of message handling in SAP systems, particularly when dealing with message types in the Application Development (AD) area. This error indicates that there is an attempt to map or process messages where the source and target message IDs are the same, which is not allowed.
  Cause:
  
  Incorrect Configuration: The source and target message IDs are configured incorrectly in the system, leading to a situation where they are identical.
  Data Entry Error: During the setup of message mappings or configurations, the same ID may have been mistakenly entered for both source and target.

  Solution:
  
  
  Check Configuration: Review the configuration settings for the message types involved. Ensure that the source and target message IDs are distinct.
  
  Navigate to the relevant transaction (e.g., WE20 for partner profiles, WE21 for port definitions) and verify the settings.
  
  
  
  Correct Data Entry: If the error is due to manual data entry, correct the IDs to ensure they are different.

  Testing: After making the necessary changes, test the message processing again to ensure that the error does not recur.
  
  
  Consult Documentation: If you are unsure about the correct message IDs to use, refer to SAP documentation or consult with your SAP Basis or functional team for guidance.
