Hi,
Lookup() is what kind of join ?

Answer Posted / ankit kansal

Lookup is used to check whether the row corresponding the incoming row is present or not and if yes then perform some logic and if not then do some other like we use to do it case of SCD2.
So, It is purely a left outer join where left table is your source table.
