• What is the cause and solution for SAP error message /SCWM/HU_WM166 - Mixed storage for storage type &1 (bin &2) failed due to insp. ID check ?

  The SAP error message /SCWM/HU_WM166 indicates that there is an issue with mixed storage in a specific storage type and bin due to an inspection ID check. This typically occurs in the context of Warehouse Management (WM) and Extended Warehouse Management (EWM) in SAP.
  Cause:
  The error is triggered when you attempt to store a handling unit (HU) in a bin that is already occupied by another handling unit that has a different inspection ID. The system enforces rules regarding mixed storage, particularly when it comes to handling units that are subject to quality inspection. If the existing handling unit in the bin has a different inspection ID than the one you are trying to store, the system will prevent the action to maintain inventory integrity and quality control.
  Solution:
  To resolve this error, you can consider the following steps:
  
  
  Check Existing Handling Units: Review the handling units currently stored in the specified bin (&2). Verify their inspection IDs and determine if they can be mixed with the new handling unit.
  
  
  Change Inspection ID: If possible, change the inspection ID of the handling unit you are trying to store to match the existing handling unit in the bin. This may involve reprocessing the handling unit through the quality inspection process.
  
  
  Use a Different Bin: If changing the inspection ID is not feasible, consider storing the new handling unit in a different bin that does not have conflicting inspection IDs.
  
  
  Adjust Mixed Storage Settings: Review the configuration settings for mixed storage in the storage type (&1). You may need to adjust the settings to allow for mixed storage under certain conditions, but be cautious as this may have implications for inventory management and quality control.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more detailed information on handling mixed storage and inspection ID checks.
  
  
  Contact SAP Support: If the issue persists and you cannot find a resolution, consider reaching out to SAP support for assistance, especially if this is impacting business operations.
  
  
  Related Information:
  
  Inspection ID: This is a unique identifier assigned to a quality inspection process in SAP. It is crucial for tracking and managing quality control in warehouse operations.
  Mixed Storage: This refers to the practice of storing different types of products or handling units in the same storage bin. While it can optimize space, it also requires careful management to avoid conflicts like the one indicated by this error.
  Warehouse Management (WM) and Extended Warehouse Management (EWM): These are modules in SAP that help manage warehouse operations, including inventory management, storage, and logistics.
  
  By following these steps, you should be able to address the error and continue with your warehouse operations.
