• What is the cause and solution for SAP error message /ACCGO/CAS_FLLW_MSG073 - System locking error occurred ?

  The SAP error message /ACCGO/CAS_FLLW_MSG073 System locking error occurred typically indicates that there is a locking issue in the system, which prevents the execution of a certain operation or transaction. This can happen for various reasons, such as concurrent access to the same data by multiple users or processes, or a previous transaction that did not release its locks properly.
  Causes:
  
  Concurrent Access: Multiple users or processes trying to access or modify the same data simultaneously.
  Unreleased Locks: A previous transaction may have encountered an error and did not release its locks.
  Long-running Transactions: A transaction that takes too long to complete can hold locks for an extended period, causing other transactions to fail.
  System Configuration: Certain configurations or settings in the SAP system may lead to locking issues.
  
  Solutions:
  
  Identify the Lock: Use transaction code SM12 to check for existing locks. You can filter by user or object to find the specific lock causing the issue.
  Release Locks: If you identify a lock that is no longer needed, you can manually delete it from the SM12 transaction. Be cautious when doing this, as it may affect other users.
  Check for Long-running Transactions: Use transaction code SM66 to monitor active processes and identify any long-running transactions that may be holding locks.
  Review Code and Processes: If the issue is recurring, review the custom code or processes that may be causing excessive locking. Optimize them to reduce lock contention.
  Increase Lock Timeout: If appropriate, consider increasing the lock timeout settings in the system configuration to allow longer wait times for locks to be released.
  Consult SAP Notes: Check the SAP Support Portal for any relevant notes or patches that may address known issues related to locking.
