Answer / venkat
here lkp transformation is perform left outer join only.
it will display matching and non matching records,but in
case of non matching(while using conn lkp)records return
default value.while using unconn lkp returns null value.

Answer / krishna
lkp is passive tr beacuse it returns 0 when condition doesn't matches .
If multiple conditions match in lkp returns first & last values.
Lkp supports Equi & non-Equi joins.
By default it is left outer join.

Answer / krithi
Using the Lookup Condition , we can only compare values
between two columns. If the data matches it returns the
default value and NULL if the data doesn't match.
We can compare using the following operators :
1) =
2)!=
3)< or <=
4)> or >=
