i added a role to a project. i staffed it with a resource. Now when i try to remove this staffing.. i get the message
"Cannot delete project role staffing"
the help is as follows
Cannot delete project role staffing
Message no. DPR_BUPA_LINK020
You are trying to delete a staffing. However, the resource of this staffing is entered as a responsible resource for at least one project element or is assigned to at least one task. The status of the assigned project element does not permit changes. This means that the links cannot be deleted and therefore, the actual staffing cannot be deleted either.
The system does not delete the project role staffing and issues appropriate messages.
Reset the status of the assigned project element so that the changes can be made.
Make sure that the links are removed by authorized users or obtain the relevant authorization from your system administrator.
But i have added the role and staffed it afresh. i am also not able to delete any newly added roles.
