• What is the cause and solution for SAP error message /SAPQUERY/BC_GLOBAL174 - Booking entry already locked (table /SAPQUERY/T200) ?

  The SAP error message /SAPQUERY/BC_GLOBAL174 Booking entry already locked (table /SAPQUERY/T200) typically indicates that a booking entry in the specified table (/SAPQUERY/T200) is currently locked by another user or process. This can happen in scenarios where multiple users or processes are trying to access or modify the same data simultaneously.
  Cause:
  
  Concurrent Access: Another user or transaction is currently editing or processing the same booking entry, leading to a lock.
  Long-running Transactions: A transaction that takes a long time to complete may hold the lock longer than expected.
  System Issues: Sometimes, system issues or bugs can lead to locks not being released properly.
  
  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 codes like SM12 (for lock entries) to identify which user or process is holding the lock. You can check the lock entries and see if you can contact the user or process to release the lock.
  Release the Lock: If you have the necessary authorizations, you can manually delete the lock entry in SM12. However, this should be done with caution, as it may lead to data inconsistencies if the other user is still processing the entry.
  Check for Long-running Processes: Use transaction SM66 to monitor active processes in the system. If you find a long-running process that is holding the lock, you may need to investigate further.
  System Configuration: If this issue occurs frequently, it may be worth reviewing the system configuration and performance to ensure that locks are being managed effectively.
  
  Related Information:
