How to compare a scaffolding field in reporting plugin against current page

Ok, it's quite easy... after some hours of trying... :D

Let's assume, we have the following snippet (in good old wikimarkup)

{list-data:page}{content-options}{list-data}

All you have to do in your report on page A is to add a content filter like:

{content-filter:data:page > collection:first|scope=@self}

This only works, as long you are not able to select mutliple pages in your list ;)
