  The SAP error message /SCWM/HU_WM151 indicates that there is an issue with mixed storage in Handling Units (HUs) due to a stock type check failure. This typically occurs in the context of Warehouse Management (WM) or Extended Warehouse Management (EWM) when trying to store different stock types in the same Handling Unit.
  Cause:
  The error is triggered when:
  
  Mixed Storage Restrictions: The system has restrictions on mixing different stock types (e.g., unrestricted stock, blocked stock, quality inspection stock) within the same Handling Unit. 
  Configuration Settings: The configuration settings in the warehouse management system may not allow for mixed storage of certain stock types.
  Stock Type Check: The stock type of the item being added to the Handling Unit does not match the stock type of the existing items in that Handling Unit.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Stock Types: Verify the stock types of the items you are trying to store in the Handling Unit. Ensure that they are compatible with each other according to your warehouse management settings.
  
  
  Review Configuration: 
  
  Go to the configuration settings in your SAP system and check the settings for mixed storage. 
  Navigate to the relevant configuration path (e.g., SPRO -> Logistics Execution -> Warehouse Management -> Mixed Storage) and review the settings for stock types.
  
  
  
  Adjust Handling Unit: If you need to store different stock types together, consider creating separate Handling Units for each stock type instead of mixing them.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific details on handling mixed storage and stock type configurations.
  
  
  User Authorization: Ensure that you have the necessary authorizations to perform actions related to stock types and Handling Units.
