• What is the cause and solution for SAP error message /SCWM/LT151 - Mixed storage '&1' at storage bin level not allowed in bulk storage ?

  The SAP error message /SCWM/LT151 Mixed storage '&1' at storage bin level not allowed in bulk storage typically occurs in the SAP Extended Warehouse Management (EWM) module when there is an attempt to store different types of products in the same storage bin that is configured for bulk storage. In bulk storage, the system does not allow mixed storage of different materials in the same bin due to the nature of bulk storage management.
  Cause:
  
  Mixed Storage Configuration: The storage type is configured to not allow mixed storage. In bulk storage, it is common to store only one type of material in a bin to avoid confusion and ensure proper inventory management.
  Storage Bin Assignment: The specific storage bin you are trying to use is already assigned to a different material, and the system does not allow mixing materials in that bin.
  Warehouse Management Settings: The settings in the warehouse management configuration may not permit mixed storage for the specific storage type or bin.
  
  Solution:
  
  Check Storage Bin Configuration: Review the configuration of the storage bin and the storage type. Ensure that the bin is set up to allow mixed storage if that is your intention. If you want to keep it as bulk storage, ensure that only one type of material is stored in that bin.
  Use Different Bins: If mixed storage is not allowed, consider using different storage bins for different materials. This is the most straightforward solution to avoid the error.
  Adjust Warehouse Management Settings: If you need to allow mixed storage in bulk storage, you may need to adjust the warehouse management settings. This can involve changing the configuration of the storage type or the specific storage bin.
  Consult Documentation: Refer to the SAP EWM documentation for detailed information on storage type configurations and mixed storage rules.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance on configuring mixed storage in EWM.
  Transaction Codes: Use transaction codes like /SCWM/PRDI (for product master) or /SCWM/LS01 (for storage bin management) to review and adjust settings.
  Training and Support: If you are unsure about making changes, consider reaching out to your SAP support team or consulting with an SAP EWM expert for assistance.
  
  By following these steps, you should be able to resolve the error and manage your storage effectively in SAP EWM.
