Field mappings

Field mappings

The Union transformation can merge data from multiple source pipelines. The sources can have the same set of fields, have some matching fields, or use parameterized field mappings.
When you work with field mappings in a Union transformation, note the following:
  • You must use input groups where the fields have the identical name, type, precision, and scale.
  • You can edit, remove, or manually add some of the output fields.
  • As part of the field mapping, you choose an input group and specify the parameter from the input group.
  • You can use parameters for fields in all input groups.
  • You can parameterize the field mapping or map by field name for each input group. At run time, the task adds an exact copy of the fields from the input group as output fields.
If you want
Data Integration
to automatically link fields with the same name and you also want to manually map fields, select the
Manual
option and click
Automap
.
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.
