Alternative / Customized WebDynpro Login Screen

Hi all,

is there a possibility to customize the SAP logon screen? We need to change the image, hide the selfregistration and give the user a chance to switch the language.

I've tried to change the UME parameters via visual admin but this doen't seem to have any effect on the SAP WebDynpro login screen.

If this is not possible, is there a way to use an own written login screen then?

Best regards,

Christian
