• What is the cause and solution for SAP error message /SCWM/POHU006 - &1 delivery items not processed due to locking errors ?

  The SAP error message /SCWM/POHU006 &1 delivery items not processed due to locking errors typically occurs in the context of the Extended Warehouse Management (EWM) module when there are issues related to data locking during the processing of delivery items. This can happen for various reasons, including concurrent processing, system performance issues, or database locks.
  Cause:
  
  Concurrent Processing: Multiple users or processes may be trying to access or modify the same delivery items simultaneously, leading to locking conflicts.
  Long-running Transactions: If a transaction takes too long to complete, it can hold locks on certain objects, preventing other transactions from accessing them.
  Database Locks: Locks at the database level can occur due to various reasons, such as long-running queries or transactions that have not been committed or rolled back.
  Configuration Issues: Incorrect configuration in the EWM system can lead to locking issues.
  
  Solution:
  
  
  Identify Locking Issues:
  
  Use transaction SM12 to check for existing locks. You can see which users or processes are holding locks on the delivery items.
  If you find unnecessary locks, you can delete them (if you have the necessary authorizations) or ask the user holding the lock to release it.
  
  
  
  Review Long-running Transactions:
  
  Check for any long-running transactions that may be causing locks. You can use transaction SM66 to monitor active processes and identify any that are taking too long.
  
  
  
  Optimize Performance:
  
  Review the performance of your EWM system. If the system is slow, it may lead to longer transaction times and increased locking issues. Consider optimizing database performance or increasing system resources.
  
  
  
  Adjust Configuration:
  
  Review the configuration settings in EWM to ensure they are set up correctly. This includes checking for any custom developments that may be causing locking issues.
  
  
  
  Retry Processing:
  
  After resolving the locking issues, you can retry processing the delivery items. Ensure that no other processes are trying to access the same items simultaneously.
  
  
  
  Consult SAP Notes:
  
  Check for any relevant SAP Notes that may address this specific error or provide additional guidance on resolving locking issues in EWM.
