SAP Netweaver 7.4 Screen

Aloha

We use Netweaver 7.4.

I have to Change "Benutzer" and "Kennwort" at the Logon Screen in Spezial "Names".

for Example :   TUDO ACC  & Passwort

I find ways to change the Pictures or "SAP Netweaver" sign, but not the place for credentials.

Thank you and best regards.
