# Enable Snowflake Table Grants

1. Navigate to the <i class="fa-gear">:gear:</i> **App Settings** page.
2. Scroll to the **Global Integrations Settings** section.
3. Ensure the **Snowflake Table Grants** checkbox is checked. *It is enabled by default.*
4. Opt to change the **Role Prefix**. *Snowflake table grants creates a new Snowflake role for each Immuta user. To ensure these Snowflake role names do not collide with existing Snowflake roles, each Snowflake role created for Snowflake table grants requires a common prefix. When using multiple Immuta accounts within a single Snowflake account, the Snowflake table grants role prefix should be unique for each Immuta account. The prefix must adhere to* [*Snowflake identifier requirements*](https://docs.snowflake.com/en/sql-reference/identifiers-syntax.html) *and be less than 50 characters.* Once the configuration is saved, the prefix cannot be modified; however, the Snowflake table grants feature can be disabled and re-enabled to change the prefix.
5. Finish configuring your integration by following one of these guidelines:
   * **New Snowflake integration**: Set up a new Snowflake integration by following the [configuration tutorial](https://documentation.immuta.com/saas/configuration/integrations/snowflake/how-to-guides/enterprise).
   * **Existing Snowflake integration (automatic setup)**: You will be prompted to enter connection information for a Snowflake user. Immuta will execute the migration to Snowflake table grants using a connection established with this Snowflake user. The Snowflake user you provide here must have Snowflake privileges to run these [privilege grants](https://documentation.immuta.com/saas/configuration/integrations/reference-guides/table-grants-overview#snowflake-privileges).
   * **Existing Snowflake integration (manual setup)**: Immuta will display a link to a migration script you must run in Snowflake and a link to a rollback script for use in the event of a failed migration. Important: Execute the migration script in Snowflake before clicking **Save** on the app settings page.
