I am using the default project list template in SharePoint 2010. the top manager will create a project and assign to someone else (manager), this manager breakdown this project into tasks and assign each task to one or more employee.
the top manager is a head of 5 departments (means 5 different subsites)
until here we don't have a problem, I've created the list under the main site so everyone in all departments (5 subsites) can see his tasks.
the problem is the project list's permission is on the list level, not on the project level. So everybody that has permission to access this list will be able to read all projects in the list not only his projects or his tasks which we don't want
my question is, can we permit the only people "created the project, created the tasks and whom the project are assigned to them" only to see this project?
I really don't know how to do that, and I appreciate your help.
