• What is the cause and solution for SAP error message /SCWM/HU_WM162 - Mixed storage for storage type &1 (bin &2) failed due to stock type check ?

  The SAP error message /SCWM/HU_WM162 indicates that there is an issue with mixed storage in a specific storage type and bin due to a stock type check. This error typically occurs in the SAP Extended Warehouse Management (EWM) module when trying to store different stock types in the same bin, which is not allowed based on the configuration settings.
  Cause:
  
  Stock Type Configuration: The storage type configuration may not allow mixed storage of different stock types. For example, if you have stock types like "Quality Inspection," "Blocked," and "Unrestricted," the system may be configured to prevent these from being stored together in the same bin.
  Bin Settings: The specific bin may have restrictions that prevent it from holding multiple stock types simultaneously.
  Warehouse Management Settings: The overall warehouse management settings may enforce strict rules regarding stock types and their storage.
  
  Solution:
  
  
  Review Storage Type Configuration:
  
  Go to the configuration settings for the storage type in EWM.
  Check the settings related to mixed storage and stock types. Ensure that the storage type allows for mixed storage if that is your requirement.
  
  
  
  Check Bin Settings:
  
  Review the specific bin settings to see if there are restrictions on the stock types that can be stored there.
  If necessary, adjust the bin settings to allow for mixed stock types.
  
  
  
  Adjust Stock Type Management:
  
  If mixed storage is not allowed for certain stock types, consider adjusting your stock management strategy. This may involve using separate bins for different stock types.
  
  
  
  Consult Documentation:

  Testing:

  User Exits and BAdIs: If your business process requires specific handling of stock types, consider implementing user exits or BAdIs to customize the behavior of the system.
