  The SAP error message /SCWM/WHO439 indicates that the system cannot take over Handling Units (HUs) for warehouse orders that are associated with a specific rule type. This error typically arises in the context of warehouse management processes, particularly when dealing with picking and handling units in SAP Extended Warehouse Management (EWM).
  Cause:
  The error can occur due to several reasons, including:

  Handling Unit Status: The status of the Handling Units may not permit them to be picked or transferred. For example, if the HUs are already assigned to another process or are in a status that does not allow picking.
  
  
  Warehouse Order Configuration: The configuration of the warehouse order may not align with the handling unit's characteristics or the picking strategy defined in the system.
  
  
  Incompatibility with Picking Strategy: The picking strategy defined for the warehouse order may not be compatible with the handling units being used.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Rule Type Configuration: Review the configuration of the rule type associated with the warehouse order. Ensure that it allows for the transfer of Handling Units. You may need to adjust the settings in the warehouse management configuration.
  
  
  Verify Handling Unit Status: Check the status of the Handling Units involved. Ensure that they are in a status that allows them to be picked. If necessary, change the status of the HUs to make them available for picking.
  
  
  Review Warehouse Order Settings: Examine the settings of the warehouse order to ensure they are correctly configured to work with the handling units. This includes checking the picking strategy and any other relevant parameters.
