Suppose you want all employees to be able to enter time on Overhead projects. However, you do not want to allow reporting on Overhead projects for all managers and lower-level employees. What do you do in this case?
Core is flexible and permission-driven to manage who sees what. This arrangement is possible in Core by keeping the Overhead project open to all employees and if using Project Assignments, make sure to assign all employees to this one. You can also turn on Employee Control for the Reports module or give report permissions only to selective employees.
