In Informatica 9.1 Lookup is active because of property - "Lookup policy on multiple match", this can be chosen as first, last, any value or all values. So now we can configure the Lookup transformation to return all rows that match a lookup condition. Hence, a Lookup transformation is an active transformation when it can return more than one row for any given input row.
However this property is available only for connected lookup, unconnected lookups are still passive.
