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 uses 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 to get the latest changes. If you do not synchronize the mapplet and you run the task, the task fails.
When you synchronize a mapplet, the updates might cause validation errors in other transformations in the mapping or mapplet. To see the assets that use the mapplet, in the Mapplet Designer, open the Actions menu and select Show Dependencies.
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
Synchronizing a mapplet
If you update the interface of a mapplet after it has been added to a Mapplet transformation, the mapplet becomes out of sync with the assets that use it. You must synchronize the mapplet to deploy the changes.
Mappings and mapplets that use the mapplet are invalid until the mapplet is synchronized. If you run a mapping task that includes a changed mapplet, the task fails.
To synchronize a mapplet from the Mapplet Designer, perform the following steps:
1Open the Actions menu and select Synchronize.
2Select the assets to update with the changes and click Update selected dependencies.
You can also synchronize the mapplet with a Mapplet transformation that uses the mapplet on the Mapplet tab of the transformation.
When you synchronize a mapplet, the changes might cause validation errors in other transformations. To see the mappings or mapplets that use the mapplet, click Actions > Show dependencies.
