Problem with User Switch

[michael_fallenbchel]

Hi experts,

I've a problem with a user switch.

I have a Web Dynpro with default user (type Service). Here I can logon with my "normal" SAP User (via function SUSR_INTERNET_USERSWITCH). Everything seem to work, sy-uname is my normal SAP user.

Now I call another Web Dynrpo (via iFrame or create_external_window). If I debug now, the "new" application has my service user as sy-uname instead of my SAP user name.

Somewhere in the link between the starting application and the called application my user must be overwritten by the default one.

Anyone an idea?

Additional Info:

When I delete the default user (SICF) from my first Application, start and login to the application (via Logon screen), my user will be forwarded to the second one.

So there must be something "wrong" with the user switch?
