• What is the cause and solution for SAP error message REORPO036 - Reservation object &1 is locked during duration of move &2 ?

  The SAP error message REORPO036 indicates that a reservation object (such as a stock reservation) is locked during the duration of a move (like a goods movement or transfer). This typically occurs when there is an attempt to modify or access a reservation that is currently being processed or is locked by another transaction.
  Cause:
  
  Concurrent Access: The reservation object is being accessed by another user or process, which locks it to prevent data inconsistencies.
  Long-running Transactions: If a transaction takes too long to complete, it can hold locks on the reservation object longer than expected.
  System Configuration: Certain configurations or customizations in the SAP system may lead to unexpected locking behavior.
  
  Solution:
  
  Wait and Retry: If the lock is temporary, waiting for a few moments and then retrying the operation may resolve the issue.
  Identify the Lock: Use transaction code SM12 to check for locks on the reservation object. You can identify the user or process that is holding the lock.
  Release the Lock: If you have the necessary authorizations, you can manually release the lock from SM12. However, be cautious when doing this, as it may lead to data inconsistencies if the other transaction is still in progress.
  Check for Long-running Transactions: Investigate if there are any long-running transactions that are causing the lock. You can use transaction SM66 to monitor active processes in the system.
  Review Custom Code: If there are custom developments or enhancements that interact with reservations, review them to ensure they are not causing unnecessary locks.
  System Performance: If locks are a frequent issue, consider reviewing system performance and tuning database settings to reduce lock contention.
