This error can arise in various scenarios, such as during the processing of distribution documents, when trying to post or change data, or when executing certain transactions.
  Causes:
  
  Concurrent Access: The most common cause of this error is that another user or process is currently accessing the same distribution data, preventing your transaction from obtaining the necessary locks.

  Identify Locking Users: Use transaction code SM12 to check for existing locks. You can identify which user or process is holding the lock and take appropriate action (e.g., contacting the user to release the lock).
  Check Long-running Transactions: Use transaction code SM66 to monitor active processes and identify any long-running transactions that may be causing locks.
