• What is the cause and solution for SAP error message /SAPAPO/SRC245 - Order cannot be created due to locking problems ?

  The SAP error message /SAPAPO/SRC245 Order cannot be created due to locking problems typically occurs in the SAP Advanced Planning and Optimization (APO) module when there are issues related to data locking. This can happen when multiple users or processes are trying to access or modify the same data simultaneously, leading to a conflict.
  Causes:
  
  Concurrent Access: Multiple users or processes are trying to create or modify the same order at the same time.
  Long-Running Transactions: A transaction that takes a long time to complete may hold locks longer than expected, preventing other transactions from proceeding.
  System Configuration: Incorrect configuration of the locking mechanism in the APO system.
  Database Locks: Locks at the database level that are not released properly can also lead to this error.
  
  Solutions:
  
  Wait and Retry: If the error is due to concurrent access, waiting for a few moments and then retrying the operation may resolve the issue.
  Check Lock Entries: Use transaction code SM12 to check for existing lock entries. If you find locks that are no longer needed, you can delete them (ensure you have the necessary authorizations and that it is safe to do so).
  Analyze Long-Running Transactions: Use transaction code SM66 to monitor active processes and identify any long-running transactions that may be holding locks.
  Review System Configuration: Ensure that the locking configuration in your APO system is set up correctly. This may involve consulting with your SAP Basis team.
  Increase Lock Timeout: If applicable, consider increasing the lock timeout settings in the system to allow longer wait times for locks to be released.
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide patches or updates.
