  The SAP error message /ISDFPS/IM_CUA020 CUA connection has been changed; all CUA IDocs are obsolete typically occurs in the context of Central User Administration (CUA) in SAP systems. This error indicates that the CUA connection has been modified, which renders all existing IDocs related to user administration obsolete. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Change in CUA Configuration: The CUA connection settings have been altered, which can happen due to changes in the system landscape, such as moving to a new server, changing the logical system name, or modifying the RFC destination.
  IDoc Status: The IDocs that were previously generated for user administration are now considered obsolete because they are linked to the old CUA configuration.
  System Synchronization Issues: If there are discrepancies between the central system and the child systems, it can lead to this error.
  
  Solution:
  
  
  Reinitialize CUA Connection:
  
  Go to the CUA configuration in the central system and ensure that the connection settings are correct.
  Check the RFC destinations and ensure they are pointing to the correct child systems.
  
  
  
  Delete Obsolete IDocs:
  
  You may need to delete the obsolete IDocs that are causing the error. This can be done using transaction WE19 (IDoc test tool) or WE02 (IDoc display) to identify and delete the obsolete IDocs.
  
  
  
  Recreate IDocs:
  
  After correcting the CUA connection, you may need to recreate the IDocs for user administration. This can be done by triggering the user synchronization process again.
  
  
  
  Check for System Updates:
  
  Ensure that all systems involved in the CUA setup are updated and consistent in terms of configuration and patches.
  
  
  
  Monitor Logs:
  
  Check the application logs (transaction SLG1) for any additional error messages or warnings that could provide more context on the issue.
