Deduplicate transformation field mappings

Deduplicate transformation field mappings

Configure field mappings to define how data moves from the upstream transformation to the Deduplicate transformation and connects to the inputs on the deduplicate asset. Configure field mappings on the
Field Mapping
tab of the
Properties
panel.
You map an incoming field to a single field on a deduplicate asset.
You can configure the following field mapping options:
Field map options
Method of mapping fields to the transformation.
Select one of the following options:
  • Manual. Manually link an incoming field to a transformation input field. Removes links for any automatically mapped field.
  • Automatic. Automatically link fields with the same name. You cannot manually link fields with this option.
  • Completely Parameterized. Use a parameter to represent the field mapping.
    Choose the Completely Parameterized option when the deduplicate asset in the transformation is parameterized or any upstream transformation in the mapping is parameterized.
  • Partially Parameterized. Configure links in the mapping that you want to enforce and use a parameter to allow other fields to be mapped in the mapping task. Or, use a parameter to configure links in the mapping, and allow all fields and links to display in the task for configuration.
Parameter
Select the parameter to use for the field mapping, or create a new parameter. This option appears when you select Completely Parameterized or Partially Parameterized as the field map option. The parameter must be of type
field mapping
.
Do not use the same field mapping parameter in more than one Deduplicate transformation in a single mapping.
Options
Controls how fields are displayed in the
Incoming Fields
and
Target Fields
lists.
Configure the following options:
  • The fields that appear. You can show all fields, unmapped fields, or mapped fields.
  • Field names. You can use technical field names or labels.
Automap
Links fields with matching names. Allows you to link matching fields and to manually configure other field mappings. The Automap options appear when you select the Manual or Partially Parameterized field map option.
You can map fields in the following ways:
  • Exact Field Name. Data Integration matches fields of the same name.
  • Smart Map. Data Integration matches fields with similar names. For example, if you have an incoming field
    Cust_Name
    and a target field
    Customer_Name
    , Data Integration automatically links the
    Cust_Name
    field with the
    Customer_Name
    field.
You can use both Exact Field Name and Smart Map in the same field mapping. For example, use Exact Field Name to match fields with the same name and then use Smart Map to map fields with similar names.
You can undo all automapped field mappings by clicking
Automap
Undo Automap
.
To unmap a single field, select the field to unmap and click
Actions
Unmap
on the context menu for the field. To unmap one or more fields that you selected, click
Unmap Selected
on the Target Fields context menu.
To clear all field mappings from the transformation, click
Clear Mapping
on the Target Fields context menu.
