• What is the cause and solution for SAP error message /SCWM/WHO437 - Pick-HUs cannot be taken over if different activity areas/queues are used ?

  The SAP error message /SCWM/WHO437 indicates that there is an issue with handling pick handling units (HUs) in the Extended Warehouse Management (EWM) module. Specifically, this error occurs when there is an attempt to take over pick handling units (HUs) that are associated with different activity areas or queues. 
  Cause:
  The primary cause of this error is that the system is trying to process handling units that are located in different activity areas or queues, which is not allowed in the current configuration. This can happen in scenarios such as:
  
  Different Activity Areas: The handling units are assigned to different activity areas, and the system does not allow the transfer of HUs between these areas.
  Different Queues: The handling units are in different queues, and the system enforces that HUs must be processed within the same queue.
  Configuration Issues: There may be configuration settings in the warehouse management system that restrict the movement of HUs across different areas or queues.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Activity Areas and Queues:
  
  Verify the activity areas and queues assigned to the handling units you are trying to process. Ensure that they are the same for all HUs involved in the operation.
  
  
  
  Reassign Handling Units:
  
  If the HUs are in different activity areas or queues, consider reassigning them to the same area or queue before attempting to take them over.
  
  
  
  Review Warehouse Configuration:
  
  Check the configuration settings in the EWM system related to activity areas and queues. Ensure that the settings align with your operational requirements and allow for the necessary flexibility.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for more detailed information on handling units, activity areas, and queues in EWM.
