Hi,

I would like to only allow the project manager to be able to create/modify or delete on his project.

I've created a new global record rule that uses the task model and check create, delete and modify options. 

This is partially working as only the project manager can modify existing task but other users can still create or delete new task in this project.

What I'm looking for is to only allow the project manager to make changes to his project.

Do you know how can I do that ?

Thanks.
