• What is the cause and solution for SAP error message /SCWM/HUGENERAL139 - Picking from HU &1 not possible since it already belongs to delivery ?

  The SAP error message /SCWM/HUGENERAL139 Picking from HU &1 not possible since it already belongs to delivery typically occurs in the context of handling units (HUs) in the SAP Extended Warehouse Management (EWM) module. This error indicates that the handling unit (HU) you are trying to pick from is already assigned to a delivery, which prevents it from being picked for another operation.
  Cause:
  
  HU Already Assigned: The handling unit (HU) is already linked to a delivery, which means it is reserved for that delivery and cannot be picked for another task.
  Incorrect Picking Process: The picking process may not be correctly configured or executed, leading to attempts to pick from an HU that is not available for picking.
  System Configuration: There may be configuration settings in the EWM system that restrict picking from HUs that are already assigned to deliveries.
  
  Solution:
  
  Check HU Status: Verify the status of the handling unit in the system. If it is indeed assigned to a delivery, you will need to either complete that delivery or unassign the HU from it if possible.
  Use the Correct HU: Ensure that you are attempting to pick from the correct handling unit that is not assigned to any delivery.
  Review Delivery Assignment: If the HU is incorrectly assigned to a delivery, you may need to check the delivery document and see if it can be modified or if the HU can be released from that delivery.
  Adjust Picking Strategy: If this is a recurring issue, consider reviewing and adjusting the picking strategy or process in your EWM configuration to prevent this situation from occurring in the future.
  Consult Documentation: Refer to SAP documentation or help resources for specific instructions on handling HUs and deliveries in your version of SAP EWM.
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like /SCWM/PRDI (for picking) or /SCWM/HU (for handling unit management) to investigate further.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance.
  User Roles and Permissions: Ensure that the user roles and permissions are correctly set up to allow for the necessary operations on HUs and deliveries.
  Training and Documentation: Ensure that warehouse staff are trained on the correct processes for handling units and deliveries to minimize errors.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a consultant who specializes in SAP EWM for further assistance.
