• What is the cause and solution for SAP error message MM_PUR_RETDEL_MSG001 - PO &1 is currently being edited in another session. Try again later ?

  The SAP error message MM_PUR_RETDEL_MSG001 indicates that a Purchase Order (PO) is currently being edited in another session. This typically occurs when multiple users or sessions attempt to access or modify the same PO simultaneously, leading to a lock on the document to prevent data inconsistencies.
  Cause:
  
  Concurrent Access: Another user is editing the same Purchase Order in a different session or transaction.
  Session Lock: The system has placed a lock on the PO to ensure data integrity while it is being modified.
  Unfinished Transactions: A previous session may not have been properly closed, leaving the PO in a locked state.
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait for a few moments and then try to access the PO again. The lock will be released once the other session is done editing.
  Check Active Sessions: If you have access, check if there are any active sessions editing the PO. You can use transaction code SM04 to see the list of active users and their sessions.
  Log Off Other Sessions: If you find that you have an active session editing the PO, log off from that session or complete the transaction.
  Contact the User: If another user is editing the PO, you may need to contact them to see when they will finish their work.
  Use Transaction SM12: If you have the necessary authorizations, you can check for locks on the PO using transaction SM12. You can view and delete locks if necessary, but be cautious as this can lead to data inconsistencies if the other user is still working on the PO.
  System Administrator: If the issue persists and you cannot identify the cause, contact your SAP system administrator for assistance. They can help investigate further and resolve any underlying issues.
  
  Related Information:
  
  Lock Mechanism: SAP uses a locking mechanism to prevent multiple users from making conflicting changes to the same data. Understanding how locks work in SAP can help in troubleshooting similar issues.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  SM04: User sessions
  SM12: Lock entries
  ME22N: Change Purchase Order
  
  
  User Training: Ensure that users are trained on how to properly close sessions and avoid leaving POs in an editable state.
  
  By following these steps, you should be able to resolve the error and access the Purchase Order as needed.
