Field mapping

Field mapping

Map fields to configure how data moves from the upstream transformation to the Output transformation.
Configure field mappings on the
Field Mapping
Field Mapping
tab includes a list of incoming fields and a list of target fields.
Mapped field names can have a maximum of 72 characters.
You can configure the following field mapping options:
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.
Controls how fields are displayed in the
Incoming Fields
Output 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.
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
    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
Undo Automap
. To unmap a single field, select the field to unmap and click
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.
  • Clear Mapping. Clears all field mappings.

How to add extra field in source table in informatica mapping and that adds fields has to reflects in entire mapping? Could you pls provide me the answer?

Informatica Documentation Team - January 18, 2023

Hi Naveen Pulivarthi,

Thanks for reaching out!

If you add an extra field in the source table and then synchronize the source (that is, click the "Synchronize" icon on the Fields tab), or you add a field to the source manually on the Fields tab, the new field should be displayed in the downstream transformations in the mapping. Source synchronization and adding source fields is described in the Source fields topic of the Transformations guide.

If this is not happening, or you are having problems with a specific mapping, please reach out to Global Customer Support.
