Managing Multiple Business Areas and Budgets in Projects

Summary:

I have two queries regarding the management of multiple business areas and budget lines in Oracle. Firstly, can a single project in Oracle have multiple business areas, each with separate budget lines? Secondly, how can Oracle track a single project with different budget lines tied to unique business areas?

Currently, for XX projects, even if there is a maintenance element that should be funded separately, all funds are allocated to the XX Allocation business area in Oracle. Ideally, we should be able to charge some amounts to the YY business area and some to the XX business area, allowing both fundings to be tracked separately.
