Answer / suneel reddy

Answers 1:
Depending upon the scenario we use the conn and unconn tr..

for e.g
In u r mapping u require same lkp multiple times, creating
lkp multiple times put it in flow is not a good idea, which
occupies more cache ...
Instead of that create one unconnectes lkp use multiple
times where ever u want , which very fast..

Answers 2:
u can use conn lookup but if u need 1 row so go for unconn
lookup coz u can
use it multiple time in same mapping from multiple
expression trn.
i hope it will help to u
