Mary, we're correcting PPP errors and all of these Alamo men are in the group "PPP With Project Account and without ProjectBox." I see you removed the project box from their profiles, but if they are not to be project managed, then the PPP and the project management need to be removed. The project, however, could remain on the Trusted List. Please advise me on this, so we can correct the error one way or another! Thanks!
