The Cleanse transformation adds a cleanse asset that you created in Data Quality to a mapping. A cleanse asset is a set of data transformation operations that standardize the form and content of your data.
You add a single cleanse asset to a Cleanse transformation. You can map one or more input fields to a cleanse asset.
A cleanse asset can perform one or more of the following operations:
•Change the character case of the input data.
•Remove leading and trailing spaces from input data.
•Remove values from the input data.
•Find and replace values in the input data.
•Merge the cleansed data from two or more input fields into a single new output field.
You can configure multiple operations in a cleanse asset, and you can add any type of operation to the asset multiple times. The mapping performs the operations on an input data field in a sequence that you define, so that a single cleanse asset can specify multiple changes to the input field data.
A Cleanse transformation is similar to a Mapplet transformation, as it allows you to add data transformation logic that you designed elsewhere to a mapping. Like mapplets, cleanse assets are reusable assets.
A Cleanse transformation does not display the logic that the cleanse asset contains or allow you to edit the cleanse asset. To edit the cleanse asset, open it in Data Quality.
