• What is the cause and solution for SAP error message KG878 - Variant was last changed on &1 by user &2 ?

  The SAP error message KG878 indicates that a variant (typically a variant of a report or a selection screen) was last changed by a specific user at a certain time. This message usually appears when there is an attempt to modify or use a variant that has been changed by another user since the last time it was accessed or saved.
  Cause:
  
  Concurrent Changes: The most common cause of this error is that multiple users are trying to modify the same variant at the same time. When one user saves changes to the variant, it locks the variant for other users.
  Outdated Version: If you are trying to use or modify a variant that has been updated by another user, you will receive this message to inform you that your version is outdated.
  
  Solution:
  
  Refresh the Variant: If you encounter this error, you should refresh the variant to get the latest version. You can do this by reloading the variant or navigating back to the variant selection screen and selecting the variant again.
  Check for Changes: If you need to make changes to the variant, check with the user who last modified it (as indicated in the error message) to understand what changes were made. This can help you avoid conflicts.
  Create a New Variant: If the changes made by the other user are significant and you need to keep your own version, consider creating a new variant instead of modifying the existing one.
  Communicate with Team Members: If this is a common issue in your team, it may be helpful to establish a protocol for variant modifications to avoid concurrent changes.
