You can automatically create and baseline an Approved Revenue Budget for a project by checking the
Baseline Funding without Budget check box in the Project Funding Inquiry window.
Note: Budget/Fund/Bill at Project or Top Task Level
You can create a revenue budget, funding source allocation and project agreement, and perform
billing at either the project or the top task level. After you have created an allocation line at either
level, you cannot change to another level. For example, if you have created a funding allocation for a
top task, you cannot create another funding allocation for the same project without entering a top
task.
