This error typically arises when there is an attempt to modify a resource's type in a way that is not permitted due to existing dependencies or configurations.

  Check Dependencies: Review any existing dependencies or assignments related to the resource. If the resource is linked to production orders, planned orders, or other planning objects, you may need to remove those links before changing the resource type.
  Resource Deactivation: If possible, deactivate the resource before attempting to change its type. This may involve temporarily removing it from any active planning scenarios.
  Consult Configuration: Check the configuration settings in the APO system to see if there are any restrictions on changing resource types. You may need to consult with your SAP Basis or APO configuration team.
  Use Alternative Approaches: If changing the resource type is not feasible, consider creating a new resource with the desired type and reassigning any relevant planning objects to this new resource.
  Documentation and Support: Refer to SAP documentation for any specific guidelines related to resource management in APO. If the issue persists, consider reaching out to SAP support for further assistance.
