SAP Screen Personas 2.0 SP3 - where is the System Selection screen?

Hello everybody,

with SAP Screen Personas 2.0 we configurated a connection from a ERP to a SCM (EWM) System. It works fine by using the System Selection Screen. We patched first to SP1, after to SP2 and recently to SP3.

But now (I'm not sure when, maybe since SP2, maybe not), I can't find the System Selection screen to access the connected SCM System. Additionallly in the SCM is no customizing-possibility for system-adjustment. So how we can get back the System Selection screen with SP3???

So, now I have no possibility to reach the SCM-System??

With SP1:

With SP3:

Thanks a lot for helping!
