roles which gives access to run create accounting from PPM for Revenue lines

So here we can stop the create accounting process to be submitted by everyone. But the create accounting process is available to resource from the following 3 places:

1. Tools —>Schedule Processes—>Create Accounting —>Subledger Accounting module—>Project Costing option to be restricted to few resources.
2. Manage Revenue Distribution—>For a line —>Post to ledger option to be restricted to few resources.
3. From Contracts—>Revenue —>Task panel—>Accounting and Close—>Create Accounting to be restricted to few resources.

What is the privilege to be removed/added or role to be customized?
