• What is the cause and solution for SAP error message /SCWM/WHO004 - Warehouse order creation called up within a process ?

  The SAP error message /SCWM/WHO004 indicates that a warehouse order creation was called up within a process, which typically means that the system is trying to create a warehouse order while another process is already in progress. This can happen in various scenarios, such as during the execution of a warehouse task or when a warehouse order is being processed.
  Cause:
  
  Concurrent Processing: The error often arises when multiple processes are trying to create or modify warehouse orders simultaneously. This can occur if there are multiple users or automated processes attempting to create warehouse orders at the same time.
  Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. If a warehouse order is being processed, it may be locked, preventing other processes from creating new orders until the current one is completed.
  Configuration Issues: There may be configuration settings in the SAP Extended Warehouse Management (EWM) that are not set up correctly, leading to conflicts during warehouse order creation.
  
  Solution:
  
  Wait and Retry: If the error is due to concurrent processing, waiting for a few moments and then retrying the operation may resolve the issue.
  Check for Active Processes: Use transaction codes like /SCWM/ORDR or /SCWM/ORDR_LIST to check for any active warehouse orders or processes that might be causing the lock. If you find any stuck processes, you may need to resolve them before retrying.
  Review Lock Entries: You can check the lock entries using transaction code SM12 to see if there are any locks on the warehouse order that are preventing the creation of new orders. If necessary, you can delete the lock entries, but this should be done with caution and typically requires administrative privileges.
  Configuration Review: Review the configuration settings in the EWM to ensure that they are set up correctly. This may involve checking the settings for warehouse order creation and processing.
  System Logs: Check the system logs (transaction SLG1) for any additional error messages or warnings that may provide more context about the issue.
