Strange issue with the filter

Hi All,

I am having a strange thing happening in one of my query.

I made a copy of one of the existing query and then applied Purchasing Doc Status = ‘C’ filter.  Now the copied query is producing more results than the original query. This query is on multiprovider.  It should actually produce the same results are lesser results. What could be the reason?.  Please have your say.

Thanks,

Sathya
