Cleanse transformation configuration

When you configure a Cleanse transformation in a mapping, you first select the cleanse asset that contains the logic to include in the transformation. Next, you map one or more incoming fields to the cleanse asset.
To configure the transformation, complete the following tasks:
    1. Connect the Cleanse transformation to a Source transformation or other upstream object.
    2. On the Cleanse tab, select the cleanse asset that you want to include in the transformation, and select one or more fields from upstream objects as inputs.
    To select the fields, click Add.
    The following image shows the options that you use to select the cleanse asset and add the input fields:
    The image shows the Cleanse tab of the transformation. The tab properties include a Select button that adds a cleanse asset to the transformation and an Add button that adds input fields that you can map to the asset.
    3. On the Incoming Fields tab, verify the incoming fields.
    By default, the transformation inherits all incoming fields from any connected upstream object in the mapping. You can define a field rule to limit or rename the incoming fields.
    4. On the Field Mapping tab, connect each field that you added on the Cleanse tab to a target field on the cleanse asset. By default, Data Integration automatically links the incoming fields with the target field.
    The cleanse asset input name might reflect the name of an input field. If so, you can use the Automap options to connect the fields.
    The following image shows the options that you can use to map the input field in the transformation:
    The image shows the Field Mapping tab of the Cleanse transformation. Use the field mapping options to identify one or more incoming fields that the transformation will read and the target fields that will carry the outcome of the cleansing operation.
    5. Verify the output field properties on the Output Fields tab.
    6. You can optionally rename the Cleanse transformation and add a description on the General tab. You can also update the tracing level for the transformation on the Advanced tab. The default tracing level is Normal.
Example 1. Synchronizing data quality assets
If you update an asset in Data Quality after you add it to a transformation, you may need to synchronize the asset version in the transformation with the latest version.
To synchronize the asset versions, open the transformation in the mapping and select the transformation name in the properties panel. For example, in a Cleanse transformation select Cleanse in the properties panel. If synchronization is necessary, Data Integration displays a message that prompts you to synchronize the assets.
When you synchronize the asset versions, Data Integration may prompt you to propagate the field attributes of the current asset to other assets in the mapping. Data Integration may display the prompt if the current asset originates in an earlier version of Data Quality.
You select the assets to which to propagate the field attributes. You can select multiple assets and propagate the attributes in a single operation.
Note: Field propagation occurs by default for assets that you create in the current version of Data Quality.
