If the interface of a mapplet changes after it has been added to a Mapplet transformation, you must synchronize the mapplet to get the changes. Synchronize a mapplet on the Mapplet tab.
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.
When you synchronize a mapplet, the updates might cause validation errors in other transformations in the mapping or mapplet.
You cannot synchronize a mapplet that you imported into Data Integration from PowerCenter or SAP.
To synchronize a mapplet, perform the following steps:
1Open the mapping or mapplet that uses the mapplet.
2Select the mapplet transformation.
3On the Mapplet tab, click Synchronize.
4Correct any resulting errors in the transformation logic.
