Configure field mappings in a Mapplet transformation to define how data moves from the upstream transformation to the Mapplet transformation. Configure field mappings on the Field Mapping tab of the Properties panel.
Note: Mapped field names can have a maximum of 72 characters.
You can configure the following field mapping options:
Mapplet Input Group
The input group for which you want to configure field mappings. This option appears when the Mapplet transformation has multiple input groups.
Field Map Options
Method of mapping fields to the Mapplet transformation. Select one of the following options:
- Manual. Manually link incoming fields to Mapplet transformation input fields. Removes links for automatically mapped fields.
- Automatic. Automatically link fields with the same name. Use when all of the fields that you want to link share the same name. You cannot manually link fields with this option.
Options
Controls how fields are displayed in the Incoming Fields and Mapplet Input 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 then manually configure other field mappings.
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.
Data Integration highlights newly mapped fields. For example, when you use Exact Field Name, Data Integration highlights the mapped fields. If you then use Smart Map, Data Integration only highlights the fields mapped using Smart Map.
Action menu
Additional field mapping options. Provides the following options:
- Map Selected. Links the selected incoming field with the selected mapplet input field.
- Unmap Selected. Clears the link for the selected field.
