• What is the cause and solution for SAP error message /SCWM/UI_PACKING179 - Empty HUs cannot be used as collective HUs ?

  The SAP error message /SCWM/UI_PACKING179 indicates that you are trying to use an empty Handling Unit (HU) as a collective Handling Unit in the SAP Extended Warehouse Management (EWM) system. This error typically arises when you attempt to pack or group HUs that do not contain any items.
  Cause:
  The primary cause of this error is that the Handling Unit you are trying to use as a collective HU is empty. In SAP EWM, collective HUs are meant to group other HUs that contain items. An empty HU cannot serve this purpose, as it does not hold any stock.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Handling Unit: Verify that the HU you are trying to use as a collective HU contains items. If it is empty, you will need to either fill it with items or select a different HU that contains stock.
  
  
  Use a Different HU: If you have other HUs that are not empty, consider using one of those as the collective HU.
  
  
  Pack Items into the HU: If you need to use the empty HU, you can pack items into it first. Once it contains stock, you can then use it as a collective HU.
  
  
  Review Packing Instructions: Ensure that your packing instructions or processes are correctly set up to avoid attempting to use empty HUs in the future.
  
  
  Consult Documentation: If you are unsure about the packing process or the handling of HUs, refer to the SAP EWM documentation or user guides for detailed instructions.
  
  
  Related Information:
  
  Handling Units (HUs): In SAP EWM, HUs are used to manage and track inventory. They can be used to group items for storage, shipping, and handling purposes.

  SAP EWM Configuration: Ensure that your EWM system is configured correctly for handling HUs and that the relevant settings for packing and handling are in place.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or refer to SAP Notes for any known issues or patches related to this error message.
