Masking Components in PowerCenter

When you generate and run a workflow from a data masking plan, the PowerCenter Integration Service creates the masking components that are required to run a data masking workflow. The PowerCenter Integration Service stores these components in the PowerCenter repository.
The PowerCenter Integration Service creates the following components to perform the data masking operations:
Important: If you edit the components that are generated from Test Data Manager in the PowerCenter Client, the session might generate unexpected results.

Mapplet Export

To implement PowerCenter masking techniques that are not available in Test Data Manager, you can create and export masking mapplets from PowerCenter to an XML file. You can import mapplets as rules into Test Data Manager.
Include one or more Data Masking transformations in the mapplet. The mapplet can be a single or multiple port mapplet. The transformations must be passive transformations. For a single input and output port mapplet, you can configure the same port as both the input and output port, and you can complete this action for multiple ports at a time when you assign a mapplet that you imported as a rule to columns in a project.
When you assign a mapplet to a columns, assign the source and target columns to the mapplet. The TDM Server applies the PowerCenter transformation within the mapplet to the columns. You can also export rules as PowerCenter mapplets.
