# Data mapping: selecting vendors

## Introduction 
In this tutorial, you'll learn how to select vendors to add as systems in the data map, using [Fides Compass](/content/docs/data-mapping/guides/compass/index.html) to populate all system information. This will get you started quickly so that you can configure privacy requests and consent.

## Prerequisites 
For this tutorial you will need:

- A Fides Cloud or Fides Enterprise account with access to Fides Compass
- The role of `Owner` or `Contributor` for your Fides organization.

## Selecting vendors 
To select vendors to add as systems in your data map:

1. Navigate to **Data map** → **Add systems**
2. Click on **Add multiple systems**
3. Locate and select all of the vendors that you wish to add
4. Click the **Add vendors** button

If a vendor appears to be greyed out and unavailable for selection, it's because this vendor already exists in the data map. To add a duplicate system for this vendor, please use the manual **Add Vendor** flow.
