Ports in a Rank Transformation

Ports in a Rank Transformation

The Rank transformation includes input or input/output ports connected to another transformation in the mapping. It also includes variable ports and a rank port. Use the rank port to specify the column you want to rank.
The following table describes the ports in a Rank transformation:
Ports
Number Required
Description
I
Minimum of one
Input port. Create an input port to receive data from another transformation.
O
Minimum of one
Output port. Create an output port for each port you want to link to another transformation. You can designate input ports as output ports.
V
Not Required
Variable port. Can use to store values or calculations to use in an expression. Variable ports cannot be input or output ports. They pass data within the transformation only.
R
One only
Rank port. Use to designate the column for which you want to rank values. You can designate only one Rank port in a Rank transformation. The Rank port is an input/output port. You must link the Rank port to another transformation.
