Describe synchronizing data by using change tracking

Synchronizing data by using change tracking is an essential aspect of developing solutions on the Microsoft Power Platform. Change tracking allows developers to track and capture the changes made to data within an application, enabling efficient synchronization and data management.

1. Enabling change tracking

To use change tracking, you must enable it on the data source you want to track. The data source can be a Common Data Service (CDS) entity, a SQL Server database, or any system that supports change tracking. The process of enabling change tracking varies depending on the specific data source but generally involves configuring the appropriate settings or applying schema changes.

2. Tracking changes in CDS entities

If you’re working with CDS entities, change tracking is available by default. Each entity in CDS has a “Modified On” field that automatically gets updated whenever a record is modified. You can leverage this field along with the built-in change tracking capabilities to identify the modified records efficiently. Additionally, you can specify the attributes that you want to track changes for, allowing granular control over the synchronization process.

3. Tracking changes in external systems

For external systems, like databases or web services, you may need to configure change tracking explicitly. This involves setting up triggers or using APIs provided by the system to capture and track changes. For example, if you’re synchronizing data from an SQL Server database, you can enable change tracking on specific tables and retrieve the changes using SQL queries.

4. Implementing change tracking in Power Automate

Power Automate provides a rich set of connectors that support change tracking out-of-the-box. To implement change tracking, you can create a flow that initiates the synchronization process. The flow can utilize connectors like SQL Server, SharePoint, Dynamics 365, or any other system that supports change tracking. By leveraging trigger conditions and filters, you can efficiently retrieve only the changed data and perform subsequent operations.

5. Processing change-tracked data

Once you’ve retrieved the changed data, you can perform various operations on it within the Power Platform, such as updating records in CDS, generating reports in Power BI, or triggering custom actions in Power Apps. By focusing only on the modified data, you can optimize performance and reduce unnecessary processing overhead.

6. Monitoring and troubleshooting

Monitoring the change tracking process is crucial for maintaining data integrity and resolving issues promptly. Power Platform provides built-in monitoring capabilities, such as Power Automate run history and session logs, to track the execution and troubleshoot any errors or failures that may occur during data synchronization.

In conclusion, using change tracking to synchronize data in Microsoft Power Platform Developer is an effective approach. By leveraging the built-in capabilities and connectors, developers can efficiently track and process the changes made to data sources. This not only streamlines the integration process but also improves performance and reduces processing overhead. Incorporate change tracking into your Power Platform solutions to enhance data synchronization and management capabilities.
