You cannot delete resource instance XXXXXX as it is already used in work execution. (WIS-4440379)

Hi, i have been trying for a while to remove a Person resource instance from a Labor resource and system will not allow me. The Person has been clocked off from any work order before trying this. I even went and completed all operations where the person had worked.

Documentation is vague, but I do not think this is intended behavior

Delete a Resource Instance:

1. On the Manage Resources page, click the resource link that you want to delete.
2. On the Edit Resource page, in the Resource Instances section, select the resource instance and click Delete.

You can't delete a resource instance that's in use in work execution.
