Maybe I"m missing something, but it doesn't work for me. There are two problems: 1. Tables T1 and T2 have the same exact structure. That means that T2 will be autoconcatenated to T1, so all the rows will be in the final table. 2. Date format is 'DD-MM-YYYY' in T1 (and qvd), but 'DD/MM/YYYY' in T2 "where" clause. Nothing will be returned by T2 alone.
