Deduplicate transformation configuration

Deduplicate transformation configuration

When you configure a Deduplicate transformation in a mapping, you first select the deduplicate asset that contains the logic to include in the transformation. Next, you map the appropriate incoming fields to the asset.
The deduplicate asset specifies the type of identity that the transformation searches for. The identity type determines the types of input field that you must connect to the transformation. For more information about the fields that the Deduplicate transformation expects, consult the
Data Quality
 user who configured the asset.
To configure the transformation, complete the following tasks:
  1. Connect the Deduplicate transformation to a Source transformation or other upstream object.
  2. On the
    Deduplicate
     tab, select the deduplicate asset that you want to include in the transformation.
    The following image shows the options that you use to select the deduplicate asset:
    The image shows the Deduplicate tab of the transformation. The tab properties include a Select button that you can use to add a deduplicate asset to the transformation.
  3. On the
    Incoming Fields
     tab, verify the fields that enter the transformation from upstream objects.
    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 one or more incoming fields to the fields on the deduplicate asset.
    The fields that you map must include data that can describe an identity of the type that the asset specifies. You must also map a GroupKey field that the transformation can use to create groups during duplicate analysis.
    The tab lists the fields from upstream objects in the
    Incoming Fields
     section and lists the fields that the asset specifies in the
    Target Fields
     section.
    The incoming field names might reflect the names of the target fields in the transformation. If so, you can use the
    Automap
     options to connect the fields.
  5. Verify the output field properties on the
    Output Fields
     tab.
    The output fields include several metadata fields that contain important information about the results of the duplication and consolidation process. For more information about the metadata fields, see Metadata fields on the Deduplicate transformation.
  6. You can optionally rename the Deduplicate 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.
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. For more information about data quality asset synchronization, see Synchronizing data quality assets.
