Visual Filter in BTP RAP List Page App

[patrick_boehm]

Hi all,

i've created in the BTP ABAP Environment an RAP based List Report Application ( ODATA V4 ) and deployed it. Now i wan't to extend this app with the "Visual Filters" and implemented the coding like in the documentation descriped in the relevant CDS Views.

E.g. like here: https://sapui5.hana.ondemand.com/sdk/#/topic/653ed0f4f0d743dbb33ace4f68886c4e.html.

But for any reason the visual filter is not shown in the UI and I don't get any errors in the activation or display of the App.
Is there maybe a restriction that I'm not aware of? 

Thank you and best regards,

Patrick
