## Enabling Data Service in Automation Suite

There are two scenarios that enable Data Service as part of your Automation Suite instance:

### The Case of a Fresh Automation Suite Installation

Data Service is provided as part of the Automation Suite basic profile, hence it is enabled automatically, regardless if you select the basic or the complete profile. To disable Data Service, follow the **Advanced installation experience** in the Automation Suite guide for the desired version.

### The Case of an Automation Suite Version Upgrade

To enable Data Service after upgrading the Automation Suite version, follow the **Managing products - Enabling or disabling Data Service** guide for the desired version.

## Enabling Data Service on Your Tenant

After you have the service ready to use as part of your Automation Suite installation, you need to provide it to your tenants too:

Follow the steps below to enable **Data Service** on your tenant.

1. Log in with your Automation Suite admin credentials and access the **Admin** page.
2. Select your tenant from the list of available tenants in the sidebar.
3. Select **Services**. The list of currently available services is displayed.
4. Select **Data Service**, then select **Add**. The **Allocate licenses** panel opens.
5. Select the number of Data Service Units (DSU) to add to your tenant, then select **Add.** You can also select **Skip**, which allocates the default selection of all available free licenses. Your tenant now updates, then returns you to the **Services** page.

Data Service is enabled in your tenant and available for use.

## Data Service Usage Limits

| Data Service resource | Limit |
