  Use Parent HU: If the operation cannot be performed on the nested HU, consider performing the operation on the parent HU instead.
  Review Configuration: Check the EWM configuration settings related to Handling Units and nested HUs. Ensure that the system is set up to allow the operations you are trying to perform.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on handling nested HUs and the operations that can be performed.
