• What is the cause and solution for SAP error message /SCWM/HU_WM030 - You are not allowed to mix different inspection lot stocks ?

  The SAP error message /SCWM/HU_WM030: You are not allowed to mix different inspection lot stocks typically occurs in the context of handling units (HUs) and inventory management within the SAP Extended Warehouse Management (EWM) module. This error indicates that there is an attempt to mix different inspection lot stocks, which is not permitted due to quality management processes.
  Cause:
  
  Inspection Lot Management: The error arises when there are multiple inspection lots associated with the stock you are trying to handle. Each inspection lot represents a specific quality inspection process, and mixing them can lead to quality control issues.
  Stock Types: Different stock types (e.g., unrestricted, quality inspection, blocked) are not allowed to be mixed if they are associated with different inspection lots.
  Handling Unit (HU) Configuration: The configuration of handling units may not allow for the mixing of stocks from different inspection lots.
  
  Solution:
  
  Separate Handling Units: Ensure that each handling unit (HU) contains stock from only one inspection lot. If you need to handle multiple inspection lots, create separate HUs for each lot.
  Check Inspection Lot Status: Review the status of the inspection lots involved. If one lot is blocked or has a different status, it may need to be resolved before mixing.
  Quality Inspection Process: Follow the quality inspection process as defined in your organization. Ensure that the stock is properly inspected and released before attempting to mix.
  Adjust Warehouse Process: If your warehouse process allows for mixing under certain conditions, you may need to adjust the configuration in SAP EWM to permit this, but be cautious as it may have implications for quality control.
  Consult Documentation: Review SAP documentation or consult with your SAP support team for specific configurations or settings that may be causing this restriction.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this error or provide additional guidance.
  Quality Management (QM) Integration: Understand how the Quality Management module integrates with EWM and how inspection lots are managed.
  Training and Best Practices: Ensure that warehouse staff are trained on handling units and inspection lot management to prevent this error from occurring in the future.
  
  If the issue persists after following these steps, it may be beneficial to engage with your SAP support team or a consultant who specializes in SAP EWM and QM for further assistance.
