In Creo 5, I am trying to delete a part from my workspace that used to belong to an assembly. I have removed this part from the assembly and erased objects. I even went as far as re-starting Creo. When I attempt to remove this part from my workspace, I receive a Windchill error stating that I must delete the next assembly if I am to delete this part. Can someone explain to me why this part is still referencing the next assembly or vice versa such that I cannot delete the part without having to delete the assembly?
Note: I have gone into the Reference View for both the part and the assembly and removed all references and dependencies to one another for each where applicable. Also, after cancelling the deletion of the part from my workspace (because Windchill would not allow the transaction), I received the attached error.
