I have a data page where I am trying to apply 2 filter criteria (Account ID and Contact ID). My record can have one of these IDs or both. The page will receive only one external parameter (either Account (aid) or Contact (cid)) and any record with either or both of these values should display if there is a match on aid of cid. However it will only display if in my record both aid and cid are populated. If I pass only the aid, it only display records with both the matching aid and a cid value populated. My records that only have the aid (which is a match), do not display.
Also, I have attempted every variation of "value required", "If empty, match blank values only", etc . . . . still no success. To get this to work, I have to create 2 data pages (1 for aid and for cid) with only 1 filter criteria. Can UI not do this in 1 data page using 2 criteria?
