• What is the cause and solution for SAP error message /CWM/MM079 - Handling units are mandatory for plant &, storage location & ?

  The SAP error message /CWM/MM079 Handling units are mandatory for plant &, storage location & typically occurs in the context of handling units (HUs) in the Warehouse Management (WM) module of SAP. This error indicates that the system requires handling units to be specified for a particular plant and storage location, but they are either missing or not properly configured.
  Cause:
  
  Configuration Settings: The system may be configured to require handling units for specific plants and storage locations. If the handling unit management is activated for the relevant plant/storage location, the system will enforce this requirement.

  Material Master Settings: The material master record for the item being processed may not have handling unit management enabled.

  Review Material Master: 
  
  Check the material master record for the item in question. Ensure that handling unit management is activated. You can do this by going to the material master (transaction MM03) and checking the relevant views.
