Do you have multiple rows in the DataProviders for DEF UH1, which sum to 700 within the report? Because filters are applied before report aggregation is done. See Why can’t I filter on a Report Aggregate? from our Reporter FAQ.
You’d have to build the DataProvider to return a single row with the value 700 in it, in order for it to be affected by the filter.
