After you create a mapplet, you can validate or edit the mapplet in the Mapplet Designer. You can also use the Designer to copy mapplets, export and import mapplets, view links between ports in a mapplet, create shortcuts to mapplets, and delete mapplets from the repository.
To create and configure a mapplet in the Mapplet Designer, complete the following steps:
Create a mapplet. Click Mapplets > Create from the menu in the Mapplet Designer. The recommended naming convention for mapplets is mplt_
Create mapplet transformation logic. Create and link transformations in the same manner as in a mapping.
