I’m using a main project with 5 sub-projects. One of the sub-projects is a resource pool. When I try to level two tasks from different sub-projects the ‘Level Selection’ menu is disabled? Why would that be the case?
Its been a while, But I believe you need to select more than one task, then select the Level Selection option. Meaning you need to make the selection before you try to click level selection.
Hope that helps
