• What is the cause and solution for SAP error message /SCWM/HU_WM165 - Mixed storage for storage type &1 (bin &2) failed due to spc. stock check ?

  The SAP error message /SCWM/HU_WM165 indicates that there is an issue with mixed storage in a specific storage type and bin due to a special stock check. This error typically occurs in the context of warehouse management in SAP Extended Warehouse Management (EWM) when trying to store different types of stock (e.g., unrestricted stock, quality inspection stock, blocked stock) in the same bin.
  Cause:
  
  Mixed Storage Restrictions: The storage type or bin may have restrictions on mixed storage. For example, certain storage types may only allow specific types of stock to be stored together.
  Special Stock Check: The system is configured to perform a special stock check, which may prevent the storage of different stock types in the same bin.
  Configuration Settings: The configuration settings for the storage type or bin may not allow mixed storage of the specific stock types involved.
  
  Solution:
  
  
  Check Storage Type Configuration: Review the configuration of the storage type in the SAP EWM system. Ensure that mixed storage is allowed for the stock types you are trying to store.
  
  Navigate to the configuration settings for the storage type and check the "Mixed Storage" settings.
  
  
  
  Review Bin Settings: Check the specific bin settings to see if there are any restrictions on the types of stock that can be stored in that bin.
  
  You can do this by navigating to the bin master data and reviewing the settings.
  
  
  
  Adjust Stock Types: If mixed storage is not allowed, consider adjusting the stock types being stored in the bin. You may need to move some stock to a different bin that allows mixed storage.
  
  
  Special Stock Configuration: If the issue is related to special stock (e.g., consignment, project stock), ensure that the configuration for handling special stock is correctly set up in the system.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more detailed information on mixed storage and special stock checks.
  
  
  Contact SAP Support: If the issue persists after checking the configuration and settings, consider reaching out to SAP support for further assistance.
  
  
  Related Information:
  
  SAP EWM Documentation: Review the official SAP EWM documentation for guidelines on mixed storage and special stock handling.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /SCWM/MON for monitoring warehouse activities and /SCWM/PR for managing stock.
  User Exits and BAdIs: If custom logic is implemented, check for any user exits or BAdIs that might affect the mixed storage behavior.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
