• What is the cause and solution for SAP error message M3844 - MARA locked by another user ?

  The SAP error message M3844, which states "MARA locked by another user," typically occurs when a user attempts to access or modify a record in the MARA table (which contains general material data) that is currently locked by another user. This locking mechanism is a part of SAP's concurrency control to ensure data integrity and prevent conflicts when multiple users are trying to access or modify the same data simultaneously.
  
  Cause:
  
  Concurrent Access: Another user is currently editing or has locked the material record in the MARA table.
  Long Transactions: A user may have an open session that is taking a long time to complete, thus holding the lock on the record.
  System Issues: Sometimes, system issues or errors can lead to locks not being released properly.
  
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait for the other user to finish their transaction and release the lock. You can try again after some time.
