• What is the cause and solution for SAP error message /SCWM/HU_WM169 - Mixed storage for storage type &1 failed due to BAdI implementation ?

  The SAP error message /SCWM/HU_WM169 Mixed storage for storage type &1 failed due to BAdI implementation typically occurs in the context of SAP Extended Warehouse Management (EWM) when there is an issue with the handling of mixed storage in a specific storage type. This error is related to the Business Add-In (BAdI) implementation that governs the rules for mixed storage in the warehouse.
  Cause:
  
  BAdI Implementation: The error indicates that the BAdI implementation for mixed storage is either not correctly configured or is returning a result that prevents mixed storage from being allowed in the specified storage type.
  Storage Type Configuration: The storage type may not be set up to allow mixed storage, or the BAdI logic may be explicitly disallowing it based on certain conditions.
  Incompatibility of Products: The products being stored may not be compatible for mixed storage as per the logic defined in the BAdI.
  
  Solution:
  
  Check BAdI Implementation: Review the BAdI implementation related to mixed storage. You can find the relevant BAdI by searching for BAdI /SCWM/EX_MIXED_STORAGE in the SAP system. Ensure that the logic implemented allows for mixed storage as intended.
  Adjust Storage Type Settings: Go to the configuration of the storage type in the EWM settings and verify that mixed storage is allowed. You can do this in the Customizing settings under:
  
  Logistics Execution > Extended Warehouse Management > Warehouse Management > Define Storage Types.
  
  
  Review Product Compatibility: Check the characteristics of the products that are being attempted to be stored together. Ensure that they meet the criteria for mixed storage as defined in the BAdI.
  Debugging: If necessary, you can debug the BAdI implementation to see what conditions are causing the failure. This may require assistance from a developer or someone with ABAP knowledge.
  Consult Documentation: Review SAP documentation or notes related to mixed storage and the specific BAdI to understand any additional configurations or considerations that may be required.
  
  Related Information:
  
  BAdI Documentation: Look for SAP notes or documentation that provide details on the BAdI /SCWM/EX_MIXED_STORAGE and its implementation.
