team_idis not automatically copied down through an entire project structure. I am fairly certain that
team_idis copied down to direct relationships (at least in 11sp12, I'm not as certain about 11sp5). However, it is not automatically copied down to related items further down the tree. Your best bet would be to create a server method
onBeforeUpdateof the project that takes the
team_idand copies it down through the whole project structure (using AML or SQL). Doing this during project creation will be trickier since
onAfterAddof the project will run before the relationships are created. You can either handle this with a scheduled method, or by adding a server method to the
onAfterAddof each relevant relationship in the tree.
