What Happens if a Projects Fee is Left Blank
If a project's Compensation field on the Budget & Revenue tab of the Projects hub has a zero or is blank and the project's revenue method uses the Compensation field or the Subject to Max operator, revenue generation does not impose a maximum on the amount of revenue that it accrues for that project.
The Subject to Max operator is available only in user-defined revenue methods.
Compensation is the only revenue field that works with the Subject to Max operator.
