Oracle PA sub-modules detail - need quick helpe

Hi,

I am new in this area & need help regarding the detail of Oracle Projects sub-modules in a way that which sub-modules are required to implement as per the scenario.

Also need confirmation of my below knowledge:

The ‘Oracle Projects Management’ has two focusing areas:

1. Project Accounting (PA)
2. Project Management

And ‘Oracle Project Management’ is a module of Oracle EBS with 5 sub-modules; where highlighted three sub-modules pertains to Project Accounting (PA):

1. Oracle Project Costing Fundamentals
2. Oracle Project Foundation Fundamentals
3. Oracle Project Management Fundamentals
4. Oracle Project Billing Fundamentals
5. Project Resource Management Fundamentals

E.g. if an org needs to implement Oracle PA to acquire a project cost accounting that can be able to capture all project expense and capital items for every strategic initiatives/programs and business improvement projects (for the org) enabling proper monitoring and accurate reporting for better decision making. Then what sub-modules are required to configure?
