When you edit a mapplet, the Mapplet Designer validates the transformation logic. When you save the mapplet, if the mapplet is valid,

Data Integration

deploys the changes to each mapping and mapplet that uses the mapplet.

Use caution when editing mapplets that are used in mappings and other mapplets. Changes to the mapplet interface result in validation errors in the mappings and mapplets that use the mapplet. To see the assets that use the mapplet, in the Mapplet Designer, open the

Actions

menu and select

Show Dependencies

.

You can make the following changes to a mapplet without affecting the assets that use the mapplet:

Change transformation names, descriptions, or properties.
Add or remove transformations in the mapplet, as long as you do not change the mapplet type from active to passive or from passive to active.

The following changes to a mapplet change the interface of the mapplet:

Add or remove transformations that change the mapplet type from active to passive or from passive to active.
Change the data type, precision, or scale of a connected input or output field.
Add or remove input or output fields
Add or remove Input or Output transformations

If you change the interface of a mapplet, you must synchronize the Mapplet transformations that use the mapplet to get the latest changes. If you do not synchronize the mapplet transformation and you run the task, the task fails.

To edit a mapplet, open the mapplet from the Explore page. You cannot edit a mapplet in a Mapplet transformation.

You cannot edit a mapplet that you imported from PowerCenter.
