Important Before you enable Data Sync, we recommend that you read [Understand What Happens When you Enable Data Sync and Connections](https://help.salesforce.com/s/articleView?id=analytics.bi_integrate_understand_enable_replication.htm&type=5&language=en_US).

1. From Setup, enter Analytics in the Quick Find box, then select **Settings**.
2. Select **Enable Data Sync and Connections**.
3. Save your changes.

Important After you enable Data Sync and Connections, make sure that you run data sync before your dataflows next run. Dataflows with sfdcDigest nodes fail until data sync has run and completed for the first time.

    Data Sync is enabled by default if you turned on CRM Analytics after the Winter ’20 release. If you turned on CRM Analytics before the Winter ’20 release, you can manually enable Data Sync. When you enable the Data Sync and CRM Analytics Connections setting, CRM Analytics looks at the sfdcDigest nodes in your existing scheduled dataflows to see which Salesforce objects and fields you’re currently extracting. Using this information, CRM Analytics enables sync for each object to extract the data separately. Understanding exactly what happens when you enable Data Sync helps you identify other actions to consider to ensure that your sync runs successfully.
