Hi Hamendra,
You are almost there but..This is only a one time activity for enrollment (in general) what we do normally. See, we got a very huge user database and in that we got a separate table for this kind of enrollment users (say we got 45000 user ids in a different table and when a user first logins into SAP this user id will be checked in the table record and it will be redirected to the enrollment page which we are developing. Is it clear?? I need the Logic on the Logon Button on SAP.
Regards
Akesh
