• What is the cause and solution for SAP error message BDDISTMODEL002 - Distribution model opened in change mode ?

  The SAP error message BDDISTMODEL002 indicates that a distribution model is currently opened in change mode, which prevents certain operations from being performed on it. This typically occurs when a user is trying to execute a transaction or function that requires the distribution model to be in display mode, but it is currently being edited by another user or session.
  Cause:
  
  Concurrent Access: Another user or session has the distribution model open for editing.
  Locking Mechanism: SAP uses a locking mechanism to prevent multiple users from making changes to the same object simultaneously. If a model is opened for changes, it cannot be accessed for other operations until it is closed.
  Session Management: Sometimes, a user may have multiple sessions open, and one of them is in change mode.
  
  Solution:
  
  Check for Open Sessions: Verify if you or another user has the distribution model open in another session. If so, close that session or save and exit the change mode.
  Use Transaction Code: You can use transaction code BD64 to check the status of the distribution model. If you are in change mode, save your changes or exit the transaction.
  Wait for Release: If another user is editing the model, you may need to wait until they finish and release the lock.
  Lock Management: If you suspect that the lock is due to a session that is no longer active, you can check the lock entries using transaction SM12. If necessary, you can delete the lock entry, but this should be done with caution and typically requires appropriate authorizations.
  Contact Administrator: If you are unable to resolve the issue, contact your SAP system administrator for assistance. They can help identify the user or session holding the lock and take appropriate action.
  
  Related Information:
  
  Transaction Codes:
