• What is the cause and solution for SAP error message /SCWM/WHO121 - &1 pick-HUs with packaging material &2 due to limit max. items/HU ?

  The SAP error message /SCWM/WHO121 indicates that there is an issue with the handling unit (HU) during the picking process in the Extended Warehouse Management (EWM) module. Specifically, the error message states that the number of items in the handling unit exceeds the maximum limit defined for that handling unit type, which is determined by the packaging material.
  Cause:
  The error occurs when:

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Packaging Material Configuration:

  Verify the maximum number of items allowed per handling unit for the specific packaging material. Adjust the limit if necessary to accommodate the quantity being picked.

  Use Different Packaging Material:
  
  If the current packaging material cannot be adjusted, consider using a different packaging material that allows for a higher number of items per handling unit.
  
  
  
  Review Warehouse Process:
  
  Ensure that the warehouse process is correctly set up to handle the quantities being picked. This may involve reviewing the picking strategy or the way handling units are managed in the warehouse.
