Using Many-to-one relationship in a drill-through

Hi,

I need to create a drill-through between two tables, joined by many-to-on relationship. The master table contains the "many" records, while the "detail" table contains single row with lot of attibutes. 

After applying the join column as the drill-through column, the "detail" table always shows all the existing records, it simply does not filter by the drill through value

If I change the roles, if I want to do a drill through from the second table on to the first, based on the same column, the drill through works perfectly, it shows the expected rows, the ones that fullfill the drill through filter.

Any ideas what I might be doing wrong?

Thanks

Viktor
