## Crawl Informatica PowerCenter assets

> Create a workflow to extract table-level and column-level lineage from Informatica PowerCenter repository exports.

Create a workflow in Atlan to extract lineage from [Informatica PowerCenter](https://docs.atlan.com/llms/connectors/informatica-powercenter/set-up-informatica-powercenter/llms.txt) repository exports. Each workflow processes the repository export archive you upload and publishes the resulting lineage against a single Atlan connection. Review the [order of operations](https://docs.atlan.com/llms/catalog/connector-capabilities/order-workflows/llms.txt) for metadata enrichment workflows before starting.

## Prerequisites

Before you begin, make sure you have:

- [Completed Informatica PowerCenter setup](https://docs.atlan.com/llms/connectors/informatica-powercenter/set-up-informatica-powercenter/llms.txt)
- A `.zip` archive of your repository XML exports ready to upload
- A `.zip` archive of parameter files if your mappings use parameters (recommended in almost all cases for accurate lineage)
- (Recommended) the source and target systems already crawled in Atlan, so lineage resolves to real assets. If they aren't cataloged yet, Atlan still publishes lineage using [partial assets](https://docs.atlan.com/llms/connectors/informatica-powercenter/what-does-atlan-crawl-from-informatica-powercenter/llms.txt) that resolve automatically once you crawl those systems

## Create crawler workflow

1. In your Atlan workspace, click **Connectors** in the left sidebar.
 * If you are using the **Old UI (Classic)**, click **New Workflow** in the top navigation.
2. Click **Marketplace**.
3. Search for **Informatica PowerCenter** and select it.
4. Click **Install**.
5. Once installation completes, click **Setup Workflow** on the same tile.

### Upload repository files

1. In the **Repository XML export** field, upload the `.zip` archive containing your PowerCenter repository XML exports. This field is required.
2. In the **Parameter files** field, upload the `.zip` archive of parameter files. This field is technically optional, but parameter files are needed for accurate lineage whenever your mappings use parameters, which is the case for most PowerCenter projects.

### Configure connection

1. Select an existing **Connection** or create a new one. This connection becomes the root for all lineage assets Atlan publishes from this workflow.
2. To change who manages this connection, update the users or groups listed under **Connection admins**.

### Configure advanced options

1. Leave the **Operator overrides (JSON)** field empty (`{}`). This field is reserved for advanced configuration in a future release; a standard crawl requires no input here.

### Run crawler

Choose to run the crawler once immediately or schedule it to run at a recurring interval.

1. Click **Run** to run once, or **Schedule & Run** to run hourly, daily, weekly, or monthly.
2. Monitor progress in the workflow execution details.

:::note
Extraction is based on the files you upload, so a scheduled run reprocesses the same archive. It doesn't pick up new PowerCenter changes. Schedule the workflow only when the uploaded input changes. To refresh lineage, re-export and re-upload your files, as described in [How do I keep lineage metadata up to date?](https://docs.atlan.com/llms/connectors/informatica-powercenter/informatica-powercenter-lineage/llms.txt), which also notes upcoming support for cloud storage-based files.

After the crawler completes, navigate to any resolved source or target asset and open the **Lineage** tab to view the data flow extracted from PowerCenter.
