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. Automatic is the default option.
Completely Parameterized. Use a parameter to represent the field mapping.
Choose the Completely Parameterized option when the cleanse 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.
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
Do not use the same field mapping parameter in more than one Cleanse transformation in a single mapping.

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.
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
and a target field
, Data Integration automatically links the
field with the
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
To unmap a single field, select the field to unmap and click
on the context menu for the field. To unmap one or more fields that you selected, click
on the Target Fields context menu.
To clear all field mappings from the transformation, click
