This error indicates that the resource you are attempting to change is currently linked to a planning object, making it non-modifiable.
  Cause:
  
  Resource Usage: The resource you are trying to modify is already assigned to a Production Planning Model (PPM) or is being used in a planning scenario.
  Locking Mechanism: SAP APO has a locking mechanism to prevent changes to resources that are actively being used in planning scenarios to maintain data integrity.

  Unlock the Resource:
  
  If the resource is locked due to ongoing planning activities, you may need to wait until those activities are completed or consult with your planning team to unlock the resource.
  
  
  
  Modify Resource:
  
  Once the resource is no longer in use or has been unlocked, you can proceed to modify the resource dimension as needed.
