How to setup WEBADMIN RFC-Connection with NWA !?

Hello,

when i test the RFC-Connection WEBADMIN on the SM59 of the SM-System i get a error (unregistered program).

In the past i can check the WEBADMIN on J2EE-Side with the Visual-Admin.

But now i only have the nwa and no visual-admin anymore.

Where can i find the RFC-Destinations in the nwa ?

I've searched on a working SM under nwa -> configuration -> destinations

But there is no WEBADMIN.

kind regards

Christoph
