Hi Venkat,
Yes.I agree to your approach. I don't have to build a FM as Standard BAPIs will serve my purpose.
I have created a Z program to fetch the details from application server and Internal tables are build.Now only i need to pass this data to BAPI_USER** to perform the actions.
"calls the RFC destinations in sequence and update the user details"
This is where am struck.I am not sure of which approach i need to for go for it.Kindly suggest some hints or let me know any of my 3 approaches mentioned above will suit the purpose.If yes which will be best.
Thanks for your kind reply.
