• What is the cause and solution for SAP error message /SCWM/WHO164 - Maximum number of consolidation groups per HU reached; WT &1 skipped ?

  The SAP error message /SCWM/WHO164 Maximum number of consolidation groups per HU reached; WT &1 skipped typically occurs in the SAP Extended Warehouse Management (EWM) module. This error indicates that a Handling Unit (HU) has reached the maximum number of consolidation groups allowed, which prevents further items from being added to that HU.
  Cause:
  
  Consolidation Group Limit: Each Handling Unit can only belong to a certain number of consolidation groups. If this limit is reached, the system will not allow additional items or warehouse tasks (WT) to be added to that HU.
  Configuration Settings: The maximum number of consolidation groups per HU is defined in the system settings. If the limit is set too low for your operational needs, you may encounter this error frequently.
  Warehouse Task Creation: When creating warehouse tasks, if the items being processed belong to different consolidation groups and the HU has already reached its limit, the system will skip the task.
  
  Solution:
  
  
  Review and Adjust Configuration:
  
  Check the configuration settings for the maximum number of consolidation groups allowed per HU. This can typically be found in the EWM customizing settings under the relevant warehouse management settings.
  If necessary, increase the limit to accommodate your operational needs.
  
  
  
  Use Different Handling Units:
  
  If the current HU has reached its limit, consider using a different HU for the additional items or warehouse tasks that need to be processed.
  
  
  
  Consolidation Group Management:
  
  Review the consolidation groups being used and see if there are opportunities to consolidate items into fewer groups, thereby reducing the number of groups associated with each HU.
  
  
  
  Monitor Warehouse Tasks:
  
  Keep an eye on the warehouse tasks being created and ensure that they are being assigned to HUs that have not yet reached their consolidation group limits.
  
  
  
  Related Information:
  
  SAP Documentation: Refer to the SAP Help Portal for detailed documentation on EWM and handling units.
  Transaction Codes: Use transaction codes like /SCWM/PRDI (for managing handling units) or /SCWM/WH (for warehouse management) to monitor and manage HUs and warehouse tasks.
  Support Notes: Check SAP Notes for any known issues or patches related to this error message.
  
  By addressing the configuration settings and managing the handling units effectively, you can resolve the error and improve the efficiency of your warehouse operations.
