# Field Maps

Field maps define how data from an external **Data Source** is read into the Aisera platform and, optionally, written back to the origianal **Data Source (SOR)**, if it is specified as the publish target in the application/bot **Details** window.

## Field Mapping

If you are using one of the pre-mapped data sources (that you can choose from the **Settings > Data Integrations** and **Settings > Data Sources** commands in the Aisera Admin UI, the fields from that data source are already mapped from that source to the entities and fields within the Aisera Gen AI platform.

You can modify or create custom maps if you are using a Generic connectior or when you want to map custom fields to fields within the Aisera Gen AI platform objects. are configured per Data Source and can be found at the bottom of the **Data Source Details** page under **Settings > Data Sources**.

The Aisera Gen AI platform provides two types of fields you can map:

**Standard Fields** are predefined Aisera platform fields. Out of the Box (OOTB) Data Sources come with standard fields pre-mapped to the Aisera Platform. You can add or modify these mappings as needed. See [New Field Mapping](/aisera-platform/adding-data-to-your-tenant/data-ingestion/field-maps/creating-new-field-maps.md) to connect a standard field to your Data Source.

**Custom Fields** are fields that you define for data that has no standard equivalent on the Aisera Platform. This could include data such as organization specific metadata, tags, or custom fields from your external systems. See [New Custom Field](/aisera-platform/adding-data-to-your-tenant/data-ingestion/field-maps/creating-a-custom-field.md) to map this data to the Aisera Platform.

Once configured, field mappings can be exported as backups or to replicate a configuration across multiple Data Sources. See [Export Fields Mappings](/aisera-platform/adding-data-to-your-tenant/data-ingestion/field-maps/exporting-field-mappings.md) and [Import Field Mappings](/aisera-platform/adding-data-to-your-tenant/data-ingestion/field-maps/importing-field-maps.md).
