Say I select table A, B, C, D, E for business and physical model. Table E have 9 FKs in total and 7 of them pointing to A/B/C/D, thus metaweb detected 7 FKs. I suppose that some of the A,B,C,D tables' FKs which are pointing to tables A-E should be detected (similar to table E), but none appears in FK tab.
