• What is the cause and solution for SAP error message KM666 - Plan data was posted ?

  The SAP error message KM666 ("Plan data was posted") typically occurs in the context of SAP Controlling (CO) when there is an attempt to post or change planning data that has already been posted. This can happen in various scenarios, such as when trying to re-enter planning data for a cost center, internal order, or other planning objects.
  Cause:
  
  Data Already Posted: The primary cause of this error is that the planning data you are trying to modify or delete has already been posted to the system. Once planning data is posted, it becomes part of the actual data, and the system restricts further changes to maintain data integrity.
  Incorrect Planning Cycle: You might be trying to post data in a planning cycle that is already closed or finalized.
  Authorization Issues: Sometimes, the user may not have the necessary authorizations to modify or delete posted planning data.
  
  Solution:
  
  Check Posting Status: Verify if the planning data you are trying to change has indeed been posted. You can do this by checking the relevant reports or transaction codes (like KP06 for cost center planning).
  Use Correct Transaction: If you need to make adjustments, consider using the appropriate transaction for adjustments or corrections, such as KP97 (for changing plan data) or KP08 (for reversing plan data).
  Open Planning Cycle: If the planning cycle is closed, you may need to reopen it (if your business process allows) to make changes. This typically requires specific authorizations.
  Consult with Your SAP Administrator: If you are unsure about the status of the data or how to proceed, consult with your SAP administrator or a colleague with experience in SAP CO. They can provide guidance on how to handle posted data.
  Authorization Check: Ensure that you have the necessary authorizations to modify planning data. If not, you may need to request additional permissions from your SAP security team.
