bapi for role management

hi

I have gone through the document for the all idm related bapi's

http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/668e6629-0701-0010-7ca0-994cb7dec5a3?overridelayout=true

Here i was not able to find BAPI related to SAP role and Profile

creation

and updation.

For e.g. is there a BAPI for adding new tcodes to a role.

Regards
