  Review Planning Hierarchy: Go through the planning hierarchy and ensure that the operations and execution plans are correctly defined and do not reference themselves.
  Adjust Configuration: If the configuration is incorrect, you may need to adjust the settings in the planning area or the relevant configuration settings in SAP.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to properly set up assignments in the Flexible Planning module.
