  Handling Unit Status: The status of the Handling Unit may not permit the unloading operation as expected.
  Incompatibility with Standard Processes: The operation being attempted may not align with the predefined processes in the system, necessitating an ad-hoc approach.

  Review Warehouse Task Configuration: Check the configuration settings for warehouse tasks in your EWM system. Ensure that the settings allow for the unloading of complex HUs as needed.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on handling complex unloading scenarios in EWM.
