Your dataset reloads five years of history every night just to pick up one day of new transactions. It works fine at a few million rows, then refreshes start timing out and the business is looking at yesterday's numbers at 11 AM.

In this live problem-solving session, we'll set up incremental refresh in Power BI end to end, so only the recent slice of data is refreshed while historical partitions stay untouched. Led by Raghavan P , Senior Data Analyst at Ford Motor Company (Global Data Insights & Analytics) and Founder of Chennai Data Circle.

What We'll Cover

✅ Where full refresh breaks down: refresh windows, memory pressure, and gateway load as fact tables grow

✅ How incremental refresh actually works: partitions, archive period vs refresh period

✅ Creating the RangeStart and RangeEnd parameters with the correct data types

✅ Applying the date filter in Power Query without breaking query folding

✅ Configuring the refresh policy in Power BI Desktop and reading the generated partitions

✅ Using "Detect data changes" so unchanged partitions are skipped entirely

✅ Publishing to the Service: the first full load, subsequent refreshes, and what to expect on timings

✅ Handling late arriving and backdated records, plus when to force a full refresh

✅ Common pitfalls: folding silently breaking, non-folding sources, time zone drift, and wrong granularity

Working knowledge of Power BI Desktop and the Power Query editor
