• What is the cause and solution for SAP error message CN126 - PS text & is already being processed ?

  The SAP error message CN126, which states "PS text & is already being processed," typically occurs in the context of Project System (PS) module when there is an attempt to change or process a project or WBS (Work Breakdown Structure) element that is already being edited or processed by another user or session.
  Cause:
  
  Concurrent Access: The most common cause of this error is that another user is currently editing the same project or WBS element. SAP locks the object to prevent data inconsistencies.
  Session Issues: Sometimes, if a user has multiple sessions open, they might inadvertently try to access the same project in different sessions.
  Background Jobs: If there are background jobs running that are processing the same project or WBS element, this can also lead to the error.
  Lock Entries: There may be lock entries in the database that are preventing access to the project or WBS element.
  
  Solution:
  
  Check for Other Users: Verify if another user is currently editing the same project or WBS element. You can use transaction code SM12 to check for lock entries and see if another user has locked the object.
  Wait and Retry: If another user is editing the project, you may need to wait until they finish and then try again.
  Close Unused Sessions: If you have multiple SAP sessions open, close any that are not in use to avoid conflicts.
  Release Locks: If you find that there are unnecessary lock entries (for example, if a session was terminated unexpectedly), you can manually delete those locks using transaction code SM12 (if you have the necessary authorizations).
  Check Background Jobs: If there are background jobs running that might be processing the project, check their status and wait for them to complete.
  Contact SAP Support: If the issue persists and you cannot identify the cause, consider reaching out to your SAP support team or SAP directly for further assistance.
