To limit or restrict activity and expense items, and employees on a project, you can use the Projects Assignments feature. To so do:
- Open the Project Assignments screen from the main menu > Projects > Assignments.
- Select a project to which you are assigning items.
- Select the items on the grid and click Add. All the selected items get assigned to that project. The same applies to the employees.
Now only these assigned items will appear in the drop-down lists of the time and expense entry screens for this project. Check the Core Help for details.
