RFC for role maintenance

Question

We are in the process of developing an ASP.NET web application which will be used to raise requests for user and role creations in SAP.
We will be making use of Sonic ESB to update SAP through IWAY SAP adapter.
IWAY SAP adapter supports RFC’s, Bapi’s & IDocs.
We are aware of RFC’s that could be used for user creation, updating and deletion.
We have NOT come across any RFC’s or Bapi’s for role maintenance                   
1) We would need RFC’s for the following requirements:
1)       To create a new role (single or composite role ).Creating a new role would include adding transactions to a role, deriving from an existing role or assigning more than one role to another role.
2)       To update a role
3)       To delete a role.
4)       To get the details of an existing role
If there are no RFC’s for the above requirement, will we need to create a custom RFC?
If we need to create a custom RFC, are there any transactions already available for the above requirements so that we could write a RFC wrapper?
2) Are there any RFC’s that would give us the complete list of roles (single or composite) in an SAP system?
3) Are there any RFC’s that would give us the complete list of transactions in an SAP system?
Presently for 2) & 3) , we are making use of RFC_READ_TABLE to read SAP tables to get the list of roles and transactions.
Thanks for your answers

Hi Nicole,
I think you are in the wrong forum.... For Guided Procedures, this is only about process roles and not roles used in the ABAP Stack.
