Error during creation of external views

Hello,

I am trying to create an analytic view modelled like below:

When I do a data preview of the same from the Modeler perspective, it works fine and I can see the data. But I switch to ABAP perspective and consume this Analytic view as an External view and try a data preview, I get an error like below:

Can someone help out as to what could be wrong here.

Thanks and regards,
