when will we go for unconnected lookup transformation in
Informatica?
Answer Posted / kamesh
The main advantage of using an unconnected lookup is the fact that you can use it in an expression/any other transformation like a “function” in other programming languages. The Lookup Cache is calculated only once as part of the session initialization and hence more efficient, since all subsequent look-ups will re-use the Cache.
