• What is the cause and solution for SAP error message INV009 - Action not possible: bill document headers already displayed ?

  The SAP error message INV009 ("Action not possible: bill document headers already displayed") typically occurs when you attempt to perform an action on a billing document that is already being displayed or processed in another session or transaction. This can happen in various scenarios, such as when trying to edit, delete, or post a billing document while it is still open in another window.
  Causes:
  
  Multiple Sessions: The billing document is open in another session or transaction, preventing further actions on it.
  Locking Mechanism: SAP uses a locking mechanism to prevent concurrent modifications to the same document. If the document is locked by another user or session, you will encounter this error.
  Incomplete Processing: If a previous action on the billing document was not completed properly, it might still be in a locked state.
  
  Solutions:
  
  Close Other Sessions: Check if the billing document is open in another session. If so, close that session or navigate away from the document.
  Check for Locks: Use transaction code SM12 to check for locks on the billing document. If you find a lock that is no longer needed, you can delete it (ensure you have the necessary authorizations to do so).
  Wait and Retry: If the document is being processed by another user, wait for them to complete their action and then try again.
  Log Off and Log Back In: Sometimes, simply logging off and back into the SAP system can clear any session-related issues.
  Contact Support: If the issue persists, it may be necessary to contact your SAP support team or system administrator for further assistance.
