BAPI to create,get Profiles and roles

Hi,

I am using the SAP RFC SDK to do the provisioning of entities in the SAP environment.

My SAP system is 6.20 .

I wanted to know if there are BAPI's which exist for the following

a)Profile creation

b)Profile Fetching

c)Role creation

d)Role Fetching

I could not find the same in the SAP IDM document provided for IAM vendors

Best Regards

Manoj
