Pipeline View for a MAP Step
For a MAP step, the Pipeline view displays a single stage of the pipeline. The Pipeline view contains two sets of variables: Pipeline In and Pipeline Out. Between these sets of variables, the Pipeline view contains a column named Transformers.

The
Pipeline In column represents input to the MAP step. It contains the names of all of the variables in the pipeline at this point in the flow.
The
Transformers column displays any services inserted in the MAP step to complete value transformations. For more information about invoking services in a MAP step, see
Working with Transformers.
The
Pipeline Out column represents the output of the MAP step. It contains the names of variables that will be available in the pipeline when the MAP step completes.
When you first insert a MAP step into your flow, Pipeline In and Pipeline Out are identical. However, if the MAP step is the only step in the flow service or is the last step in the flow service, Pipeline Out also displays the variables declared as output in the flow service.
