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.
