# Job Step: LibraryDeltaExport

**Type ID:** `LibraryDeltaExport`  
**Scope:** Organization (add to an organization-level job flow)  
**Category:** Standard / system job step (Export)

Creates Delta Export for Libraries. Support must be contacted to enable delta exports.

This is a built-in (standard) job step provided by the B2C Commerce platform. Add it to a job flow in **Business Manager → Administration → Operations → Jobs**, or reference it by its type ID in a `jobs.xml` flow inside a site-import archive.

## Configuration Parameters

| Parameter | Required | Default | Allowed Values | Description |
| --- | --- | --- | --- | --- |
| `Consumers` | Yes | — | — | Comma Separated List of consumers. Limit of 1000 characters |
| `ExportFile` | Yes | — | — | Delta Export name and Export file name and path relative to 'IMPEX/src'. |
| `LibraryIDs` | Yes | — | — | Comma Separated list of Library Content Ids to be exported. Limit of 1000 characters |

## Working With IMPEX Files

This step writes a file into the instance IMPEX area (typically under `IMPEX/src/...`). The produced file can be consumed by a later step in the same flow (for example a replication or a custom processing step) or downloaded via WebDAV. See the `b2c:b2c-custom-job-steps` skill for IMPEX hand-off patterns.
