How to Use Snapshots to Show Data History in Power BI (Track Changes) Easily 2026

By Impran M N

Sometimes a single point-in-time report isn't enough, and you need to see how figures like sales or inventory have changed over time. This guide covers how to use the snapshot approach in Power BI to capture and compare historical data. It's useful for teams that need trend visibility for compliance, forecasting, or performance tracking.

01Set up snapshots in Power BI

Configure your report or data pipeline to periodically capture and store a snapshot of your data at set intervals.

02View historical data

Access the stored snapshots within your report so you can see what your data looked like at different points in time.

03Compare data over time

Build visuals that place snapshots side by side, letting you compare metrics like quarterly sales or inventory levels across periods.

04Automate ongoing reporting with snapshots

Set up your snapshot process to run automatically so historical comparisons stay current without manual data capture.

05Apply it to a business scenario

Use snapshots for a practical case, such as tracking changes in inventory levels or comparing quarterly sales performance.
