• What is the cause and solution for SAP error message MDG_GN009 - Only one target system is allowed for a temporary subroutine pool ?

  The SAP error message MDG_GN009 indicates that there is an issue with the configuration of a temporary subroutine pool in the context of Master Data Governance (MDG). This error typically arises when there is an attempt to define multiple target systems for a temporary subroutine pool, which is not allowed.
  Cause:
  The error occurs due to the following reasons:
  
  Multiple Target Systems: The configuration for a temporary subroutine pool is set up to point to more than one target system, which is against the rules of how temporary subroutine pools are designed to function.
  Incorrect Configuration: There may be a misconfiguration in the MDG settings or in the way the subroutine pool is defined.
  Transport Issues: If the transport requests are not correctly set up, it may lead to inconsistencies in the target system definitions.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Check Configuration:
  
  Go to the relevant configuration settings in the MDG system.
  Ensure that the temporary subroutine pool is configured to point to only one target system. You can do this by navigating to the relevant customizing transaction (e.g., SPRO) and checking the settings under Master Data Governance.
  
  
  
  Review Subroutine Pool Settings:
  
  Access the transaction SE80 (Object Navigator) or SE37 (Function Module) to review the subroutine pool.
  Ensure that the subroutine pool is correctly defined and that it does not reference multiple target systems.
  
  
  
  Transport Management:
  
  If the issue arose after a transport, check the transport request to ensure that it has been correctly imported into the target system.
  Verify that the transport does not contain conflicting definitions for the subroutine pool.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to MDG and subroutine pools for any specific guidelines or updates that may address this issue.
