Connecting to Mapplet Output Groups

Each Output transformation displays as an output group when you use a mapplet in a mapping. Connect the mapplet output ports to the mapping pipeline. Use Autolink to connect the ports.

Use the following rules and guidelines when you connect mapplet output ports in the mapping:

When a mapplet contains a source qualifier that has an override for the default SQL query, you must connect all of the source qualifier output ports to the next transformation within the mapplet.

If the mapplet contains more than one source qualifier, use a Joiner transformation to join the output into one pipeline.

If the mapplet contains only one source qualifier, you must connect the mapplet output ports to separate pipelines. You cannot use a Joiner transformation to join the output.

If you need to join the pipelines, you can create two mappings to perform this task:

Use the mapplet in the first mapping and write data in each pipeline to separate targets.

Use the targets as sources in the second mapping to join data, then perform any additional transformation necessary.
