cannot limit access right of Project Manager as a simple viewer for a defined project - by: cmarechal

Hi,
a have a problem of access rights i can't solve :

User1 has a profile of Project Manager

but in the project1 he is only a viewer (read only access - profil of viewer in the project affectations)

-when user1 is connected to Projeqtor he can create elements (as a Project Manager) which are for its own projects. But he cannot create element as element of the project1. By now; everything is normal.

-when user1 uses the project combo box at the top-left of the screen and go to the project1, on the filtered screen of planning (planning of project1) he can create sub-project, activities and milestones linked to project1. Is it normal ?

once created, user1 cannot delete this elements belonging to project1 even if he has them himself created ! Strange...

thanks for your help,

Christophe
