• What is the cause and solution for SAP error message 0Q103 - RFC version and local version are incompatible ( &1 <> &2 ) ?

  The SAP error message 0Q103 indicates that there is an incompatibility between the RFC (Remote Function Call) version of the calling system and the local version of the target system. The message format typically shows two versions: &1 represents the version of the calling system, and &2 represents the version of the target system.
  Cause:
  
  Version Mismatch: The most common cause of this error is that the two systems (the one making the RFC call and the one receiving it) are running different versions of the SAP software. This can happen if one system has been upgraded while the other has not.
  Incompatible Function Modules: If the function modules being called have been changed or updated in one system but not in the other, this can lead to version incompatibility.
  Network Issues: Sometimes, network issues or misconfigurations can lead to incorrect version information being reported.
  
  Solution:
  
  Check SAP Versions: Verify that both systems are running compatible versions of SAP. You can check the version by using transaction code SLICENSE or SPAM in both systems.
  Upgrade Systems: If there is a version mismatch, consider upgrading the older system to match the version of the newer system.
  Check Function Modules: Ensure that the function modules being called are compatible. You can do this by checking the function module's attributes in transaction SE37 or SE80.
  Regenerate RFC Destinations: If the RFC destination is outdated, you may need to regenerate it. You can do this in transaction SM59 by deleting and recreating the RFC destination.
  Check for Notes: Look for SAP Notes related to RFC issues or specific function modules that may have known compatibility issues.
  Test Connectivity: Use transaction SM59 to test the RFC connection and ensure that it is working correctly.

  Documentation: Review SAP documentation for details on RFC and function module compatibility.
  
  By following these steps, you should be able to identify and resolve the cause of the RFC version incompatibility error.
