Reg: Login to Web Dynpro

Hi All,

Need some help. In my requirement i need to know the User Name who has logged into SAP ABAP WEBDYNPRO.

I mean i don't need the SAP Logon Details like generally we get them when we use SY-UNAME.

Please Provide me Portal Login Details. Any code or setting's related to it. Let me know is this possible.

Thanks,

Sandy.
