• What is the cause and solution for SAP error message /SCWM/HUGENERAL079 - Source and destination HU must be different ?

  The SAP error message /SCWM/HUGENERAL079 indicates that there is an issue with handling units (HUs) in the SAP Extended Warehouse Management (EWM) system. Specifically, the error states that the source and destination handling units must be different. This typically occurs during processes such as stock transfers, picking, or putaway when the system expects the source and destination HUs to be distinct.
  Cause:
  
  
  Same Handling Unit: The most common cause of this error is that the system is trying to perform an operation where the source and destination handling units are the same. For example, if you are trying to move stock from one location to another but mistakenly specify the same HU for both the source and destination.
  
  
  Incorrect Configuration: There may be configuration issues in the warehouse management settings that do not allow for the same HU to be used in both source and destination fields.
  
  
  User Input Error: The user may have inadvertently selected the same HU for both the source and destination during a transaction.
  
  
  Solution:
  
  
  Check Handling Units: Verify the handling units being used in the transaction. Ensure that the source and destination HUs are indeed different. If they are the same, select a different destination HU.
  
  
  Review Transaction Steps: Go through the steps of the transaction to ensure that the correct HUs are being selected. If you are using a transaction code, double-check the input fields.
  
  
  System Configuration: If the issue persists, check the configuration settings in the EWM system. Ensure that the settings allow for the correct handling of HUs and that there are no restrictions preventing the use of different HUs.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on handling units and the processes you are working with.
