Hai frnds,
According to my knoweledge,active t/f means which changes the number of rows that can pass through it.
coming to why union t/s is active.......because union t/f merges the data which is coming from two sources,it means that it summarizes the data which is passing through union t/f,with this the no.of rows coming from that will be less....
so it is an active t/f...
Thanks.....Raji
