• What is the cause and solution for SAP error message /SCWM/UI_PACKING404 - Mix of transit HUs and normal HUs in HU-hierarchy is not allowed ?

  The SAP error message /SCWM/UI_PACKING404 indicates that there is a mix of transit Handling Units (HUs) and normal HUs in the HU hierarchy, which is not allowed in the SAP Extended Warehouse Management (EWM) system. This error typically arises when you are trying to pack or process HUs that belong to different categories in a single operation.
  Cause:
  
  Mixing HUs: The primary cause of this error is that you are attempting to pack or manage HUs that are classified differently (i.e., some are transit HUs while others are normal HUs).
  Hierarchy Structure: The HU hierarchy is structured in such a way that it expects all HUs to be of the same type. Mixing different types violates this structure.
  Incorrect Configuration: There may be configuration issues in the warehouse settings that allow for the creation of mixed HUs.
  
  Solution:
  
  Check HU Types: Review the HUs you are trying to pack. Ensure that all HUs in the hierarchy are of the same type (either all transit or all normal).
  Separate HUs: If you have a mix of HUs, separate them into different packing operations. You can either:
  
  Create a new packing operation for the transit HUs.
  Create a new packing operation for the normal HUs.
  
  
  Review Packing Strategy: Ensure that your packing strategy does not inadvertently mix different types of HUs. Adjust the strategy if necessary.
  Configuration Review: Check the configuration settings in the EWM system to ensure that the handling of HUs is set up correctly. This may involve reviewing the settings for handling units and their types.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on handling HUs in EWM.
  
  Related Information:
  
  Handling Units (HUs): In SAP EWM, HUs are used to manage inventory and logistics processes. They can be classified as normal HUs or transit HUs based on their status and purpose.
  EWM Configuration: Proper configuration of EWM is crucial for managing HUs effectively. This includes defining HU types, packing strategies, and warehouse processes.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling HUs in EWM.
  
  By following these steps, you should be able to resolve the error and ensure that your packing operations are compliant with the system's requirements.
