Editing a mapplet

Editing a mapplet

Edit a mapplet in the Mapplet Designer. To edit a mapplet, open the mapplet from the Explore page.
When you edit a mapplet, the Mapplet Designer validates the transformation logic. If a mapplet is valid when you save it,
Data Integration
 deploys the changes to each mapping and mapplet that use the mapplet.
Use caution when you edit mapplets that are used in mappings and other mapplets. If you edit the mapplet interface, mappings and mapplets that use the mapplet will have validation errors. To resolve the validation errors, 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 see the assets that use the mapplet, in the Mapplet Designer, open the
Actions
 menu and select
Show Dependencies
.
You cannot edit a mapplet in a Mapplet transformation, and you cannot edit a mapplet that you imported from PowerCenter.

Changes that affect dependencies

Changes to a mapplet might affect the mappings and mapplets that use the mapplet.
The following changes to a mapplet do not affect 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 and affect the assets that use 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
