portal iview error "data source contains no columns which can be displayed"
we recently upgraded our portal and now come across this error.
I've read SAP Notes 1349649 - PDV: Use in EP6, EP7, and releases higher than EP7
From what I see in the notes we have to use Abap webdynpro iviews.
But the explanation ends there. How am i supposed to call the PDV-application/query/function from a webdynpro iview?
Is there anyone that experienced (and solved) this before?
Thanks in advance,
