Any Function Module to Authenticate SAP User?

[Former Member]

Hi Experts,

I have a web service that need to authenticate SAP user before the user call the web service.

So, is there any function module to authenticate the SAP user?

Thank you.

Hi, Check with the below one.

BAPI_USER_EXISTENCE_CHECK

This function has a export parameter 'RETURN' which lets you know if the user exits or not in SAP.

If RETURN-ID = '01' and RETURN-NUMBER = '088', user exits in SAP system.

If RETURN-ID = '01' and RETURN-NUMBER = '124' , user does not exists in SAP.
