Merge units allow you to consolidate parameters from two or more sources (including Transform units) into a single output.
If a Decision unit is used in a pipeline, you often need to include a Merge unit to consolidate the parameters from multiple branches of the pipeline. The consolidated output then becomes available for endpoints or other flow units in a pipeline.
The following screenshot shows a Merge unit used in a pipeline.
To use a Merge unit in a pipeline, follow these steps.
In a pipeline, drag a line from a unit and drop it onto a connection indicator.
From the Select unit to place pane, click Merge Unit to add it to the pipeline.
Connect a data source (or Flow unit) to the Merge unit, passing over the connection indicator.
Drag a line from the Merge unit to another unit on the pipeline (or Endpoint as in this example)
