Mapplet

The Mapplet Designer appears with an Input transformation and an Output transformation on the canvas.

Specify the mapplet name and location.

The default name for the mapplet is

Mapplet

followed by a sequential number.

If the

Explore

page is currently active and a project or folder is selected, the default location for the asset is the selected project or folder. Otherwise, the default location is the location of the most recently saved asset.

You can change the name or location after you save the mapping using the

Explore

page.

Optionally, enter a description for the mapplet.

When you use the mapplet in a Mapplet transformation, the description appears in the

Mapplet

tab.

Optionally, filter the transformations in the transformation palette.

Configure the mapplet input.

Input can be a Source transformation, an Input transformation, or both. If you use an Input transformation, add input fields for the fields you want to pass to the mapplet.

Add transformations to the mapplet.

Configure the mapplet output.

Output can be a Target transformation, an Output transformation, or both. If you use an Output transformation, add output fields for the data you want to pass to the downstream transformation.

Validate the mapplet.

Resolve errors on the appropriate tab in the

Validation

panel.

Resolve errors on the

Mapping

tab to use the mapplet outside of advanced mode.

Resolve errors on the

Mapping (Advanced Mode)

tab to use the mapplet in advanced mode.
