• What is the cause and solution for SAP error message /SCWM/UI_PACKING181 - HU &1 has reference to a collective HU. Packing is not allowed ?

  The SAP error message /SCWM/UI_PACKING181 indicates that the handling unit (HU) you are trying to pack is associated with a collective handling unit (collective HU). In SAP Extended Warehouse Management (EWM), collective handling units are used to group multiple handling units together, and certain operations, such as packing, are restricted for these collective HUs.
  Cause:
  The error occurs because:
  
  The handling unit (HU) you are trying to pack is part of a collective handling unit.
  The system does not allow packing operations on HUs that are part of a collective HU.
  
  Solution:
  To resolve this error, you can consider the following steps:
  
  
  Check the Handling Unit: Verify if the HU you are trying to pack is indeed part of a collective HU. You can do this by checking the HU details in the system.
  
  
  Unpack the Collective HU: If you need to pack the individual HUs, you may need to unpack the collective HU first. This can typically be done using the unpacking function in the EWM system.
  
  
  Create a New Handling Unit: If the packing operation is necessary, consider creating a new handling unit that does not reference the collective HU.
  
  
  Review Packing Strategy: Ensure that your packing strategy aligns with your warehouse processes. If collective HUs are frequently causing issues, you may need to adjust your packing strategy or handling unit management.
  
  
  Consult Documentation: Refer to SAP documentation or your organization's SAP support team for specific instructions related to handling units and packing processes.
  
  
  Related Information:
