Hi,
Very delayed reply, but still this may help others.
Yes it will not be removed, unless you assign a dummy position/person which is not assigned with any PD profile and run the report RHPROFL0 for that dummy position for which the User ID is maintained with that dummy person in IT105.
And then run the report RHBAUS02 for the user id with threshold and delete checked. After which run the reports RHBAUS01 & RHBAUS00 for that user id. So that this user id will be completely removed.
