Answer Posted / venkateshmalneni
If the source1 has 10 records and the it contains 3 records
and the same 3 records are in the second source,the second
source contains 10 records if we want to join them using union
t/r then the output is 17 records instead of 20 records.
thats why we say that UNION T/R is active t/r
