Hi Experts,
I created a Fiori App( List Report - Object Page ) using Fiori Elements and ABAP RAP Programming.
My App is hierarchical, means I navigate from List Report of Headers to Object Page with header data and having also a list of items in a facet below. How can I add filters there similar to the List Report Page of the headers. A Filterbar like this:

But on item level:

I changed the Metadata extension file but this doesn't help. I added:
@UI: {
selectionField: [{position: 20 }],
lineItem: [{ position: 60, importance: #HIGH, label: 'Class' }]
}
Fieldname;
Thanks for any help. :-)
Best regards, Thomas
