Answer / sri
Lookup is a transformation in Informatica which is mainly
used for obtaining the "Key" values from the dimensions.
Lookup can be connected or unconnected. If it is
unconnected then it can be used as a function but it can
return only one value.
Where as connected lookup return more than one value.
Lookup contains:
1. <Input Column/Value>
2. <Output Column(s)>
3. <Condition>
