Submitted by: Administrator

We have mainly tree ports Inport, Outport, Variable port. Inport represents data is flowing into transformation. Outport is used when data is mapped to next transformation. Variable port is used when we mathematical calculations are required. If any addition i will be more than happy if you can share.

We can use variable ports to store values of previous records which is not otherwise possible in Informatica.
