• What is the cause and solution for SAP error message /SCWM/WHO518 - HU &1 was reassigned to warehouse order &2 ?

  The SAP error message /SCWM/WHO518 HU &1 was reassigned to warehouse order &2 typically occurs in the context of warehouse management processes in SAP Extended Warehouse Management (EWM). This error indicates that a Handling Unit (HU) has been reassigned to a different warehouse order, which can lead to inconsistencies in the system if not handled properly.
  Cause:
  
  Reassignment of Handling Units: The error usually arises when a Handling Unit (HU) that is already assigned to a warehouse order is attempted to be processed or reassigned to another warehouse order.
  Concurrent Processing: If multiple users or processes are trying to work with the same HU simultaneously, it can lead to this error.
  System Configuration: There may be specific configurations or settings in the warehouse management system that restrict the reassignment of HUs.
  
  Solution:
  
  Check HU Assignment: Verify the current assignment of the Handling Unit (HU) in question. Ensure that it is not currently assigned to another warehouse order.
  Release the HU: If the HU needs to be reassigned, it may need to be released from the current warehouse order first. This can typically be done through the warehouse management transaction codes or through the EWM interface.
  Review Warehouse Orders: Check the status of the warehouse orders involved. If the warehouse order to which the HU is being reassigned is not in a suitable status (e.g., it is already completed or closed), you may need to adjust the order status.
  Avoid Concurrent Processing: Ensure that no other users or processes are trying to access or modify the same HU at the same time.
  Consult Documentation: Refer to SAP documentation or help resources for specific instructions related to your version of SAP EWM, as the steps may vary based on the system configuration.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in SAP EWM, such as /SCWM/PRDI for processing inbound deliveries or /SCWM/PRDO for outbound deliveries.
  SAP Notes: Check for any SAP Notes related to this error message, as they may provide additional insights or patches that address known issues.
  User Authorization: Ensure that the user has the necessary authorizations to perform actions on the specified HUs and warehouse orders.
  System Logs: Review system logs for any additional error messages or warnings that may provide more context about the issue.
  
  If the problem persists after following these steps, it may be beneficial to consult with your SAP support team or a technical consultant who specializes in SAP EWM for further assistance.
