User wants to mark all time entries charged to a specific project as non-billable.
There is a simple way to accomplish this in Core using Project Assignments. You can mark the activities as non-billable, and that will make the associated time entries non-billable. To do so:
- Open the Project Assignments screen from the main menu > Projects > Assignments.
- Assign the activities that can be used for this specific project.
- You can also select All Group if there are no exceptions and flag it as non-billable.
All time entries entered for this project will default to non-billable after this.
