Hi @tomgreenwood,
I have added to my user a specific object group (AG_65000894) and I have resource 82 with that same object group.
When I uncheck the allowed option and leave only the default option for ViewAllResources permission I am not able to see that resource in the Gantt, even though I am able to see it in Resources menu.
Is this normal behavior? If I understand correctly that by Resources menu you mean the Resources screen in the planning workspace then yes this is correct. Because your user is in the same object group as resource 82 you can still see this user in the planning workspace. As ViewAllResources is off you can only see resources in the Resources screen in the scheduling workspace (the Gantt) that you add in the Viewable Resources tab. If resource 82 is not in this list you will not see them in the Gantt.
Also if then I add another resource with another object group (one that is not added to my user) to the Viewable Resources tab, I am able to see this new resource in Gantt and not in resources menu, but I still don't see the first resource in Gantt.
This makes sense too because you have added the resource id to the list of viewable resources so you can see them in the Gantt (as above this related to resources you can view in the schedule, not the planning workspace). You can’t see them in the planning workspace because your user doesn’t belong to the same group as the Resource.
The administration guide has a section on restricting access to resources and activities where you can find more information.
Thanks,
Tom
