This error indicates that you are trying to pack one handling unit (HU) into another handling unit that is currently involved in a storage process, which is not permitted.

  Active Storage Process: The target handling unit (HU &2) is currently part of an active storage process (e.g., it may be in the process of being put away, picked, or moved).

  Check Storage Process: Verify if the target handling unit (HU &2) is indeed involved in an active storage process. You can do this by checking the status of the HU in the system.
  
  
  Complete or Cancel the Storage Process: If the storage process can be completed or canceled, do so. This will free up the target HU for packing operations.
  
  If the process is a putaway, ensure that the items are successfully put away.
  If it is a picking process, ensure that the picking is completed or canceled.
  
  
  
  Use a Different HU: If you cannot complete or cancel the storage process, consider using a different handling unit that is not involved in any active processes for your packing operation.
  
  
  Review Configuration: If this error occurs frequently, review your warehouse management configuration to ensure that handling units and storage processes are set up correctly.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more detailed information on handling units and storage processes in EWM.
