The Nested Pipeline is a deprecated feature. Use the Pipeline Execute Snap to create child Pipelines and Resumable Pipelines to achieve exactly-once-delivery. |
...
Nested pipelines, or subpipelines, include one or more pipelines along with Snaps to perform data integration. The main advantage of nested pipelines is reusability. There are certain data integration tasks that require a combination of Snaps at multiple places. To avoid constructing the same combination of Snaps multiple times, a pipeline is saved with these Snaps. The saved pipeline can be later used as a Snap, called a subpipeline or child pipeline.
Nested pipelines can have any number of subpipelines, the same or different ones at any place inside the parent pipeline. While no specific limit is set on the number of levels of nesting supported, as it would vary depending on the pipelines included, SnapLogic has tested with five to six levels of nesting.
If, when placed on another pipeline's workbench, a subpipeline does not have any connection points, you must edit the views of a subpipeline to allow connections to it.

| Note |
|---|
Multiple nested pipelines writing output to a single file is not supported. |
Parameters
The nested pipelines accept parameters similar to the normal pipelines.
| Note |
|---|
If a subpipeline has parameters, then they override the parameters set on the entire parent pipeline. |
