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:
Mappings
Transformations
Mapplets
Sessions and workflows
If you edit the components that are generated from Test Data Manager in the PowerCenter Client, the session might generate unexpected results.
