• What is the cause and solution for SAP error message /SCWM/UI_GR081 - External HU number can only be used if exactely one HU should be added ?

  The SAP error message /SCWM/UI_GR081 indicates that there is an issue with handling Handling Units (HUs) in the Extended Warehouse Management (EWM) module. Specifically, this error occurs when you attempt to add an external Handling Unit (HU) but the system finds that there is not exactly one HU that can be added. This can happen in various scenarios, such as during goods receipt, transfer, or other warehouse operations.
  Cause:
  
  Multiple HUs Found: The system may have found multiple HUs that match the external HU number you provided, which leads to ambiguity about which HU should be added.
  No Matching HUs: Conversely, if there are no HUs that match the external HU number, the system cannot proceed.
  Incorrect HU Status: The status of the HUs may not allow them to be added to the process you are trying to execute.
  Data Entry Error: There may be a typographical error in the external HU number you entered.
  
  Solution:
  
  Check External HU Number: Verify that the external HU number you are entering is correct and corresponds to exactly one existing HU in the system.
  Review Existing HUs: Use transaction codes like /SCWM/HU to list existing HUs and check if the external HU number you are trying to use is present and unique.
  Check HU Status: Ensure that the status of the HU allows it to be added to the current process. For example, it should not be in a status that prevents it from being used (e.g., blocked, damaged).
  Use Unique HU: If multiple HUs are found, you may need to specify additional criteria to narrow down the selection or choose a specific HU from the list.
  Consult Documentation: Refer to SAP documentation or help resources for more details on handling HUs in EWM.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in EWM, such as /SCWM/HU for handling units, /SCWM/PR for processing requests, and others that may help in managing HUs.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  User Authorization: Ensure that you have the necessary authorizations to perform operations involving HUs.
  Training and Documentation: Consider reviewing training materials or documentation related to EWM and handling units to better understand the processes involved.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a technical consultant who specializes in EWM for further assistance.
