• What is the cause and solution for SAP error message /SAPNEA/J_SC002 - Exceptional material table locked ?

  The SAP error message /SAPNEA/J_SC002 Exceptional material table locked typically indicates that the system is unable to access or modify the exceptional material table due to it being locked. This can happen for several reasons, including concurrent access by multiple users or processes, or a previous transaction that did not complete properly.
  Causes:
  
  Concurrent Access: Multiple users or processes are trying to access or modify the same material data simultaneously.
  Unfinished Transactions: A previous transaction that was supposed to unlock the table did not complete successfully, leaving the table in a locked state.
  System Errors: Technical issues or bugs in the SAP system can also lead to locking problems.
  
  Solutions:
  
  Wait and Retry: If the lock is due to concurrent access, waiting for a few moments and then retrying the operation may resolve the issue.
