Type of Lookup
Input port. Create an input port for each lookup port you want to use in the lookup condition. You must have at least one input or input/output port in each Lookup transformation.
Output port. Create an output port for each lookup port you want to link to another transformation. You can designate both input and lookup ports as output ports. For connected lookups, you must have at least one output port. For unconnected lookups, select a lookup port as a return port (R) to pass a return value.
Lookup port. The Designer designates each column in the lookup source as a lookup (L) and output port (O).
