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

for mappings in or outside of advanced mode

when you save it,

Data Integration

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

For example, if the mapplet is valid both in and outside of advanced mode and you change the interface of the mapplet so that it's only valid outside of advanced mode,

Data Integration

deploys the changes to all mappings 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 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

.

You cannot edit a mapplet in a Mapplet transformation, and you cannot edit a mapplet that you imported from PowerCenter.
