Incremental Refresh with Power BI Pro License

Hii Khushboobarai 

Your current setup (multiple folders + append + main query) is the reason incremental refresh is not working. Incremental refresh only works when a single table has a proper Date column filtered using RangeStart/RangeEnd with query folding  folder-based appends usually break this.

In your case, since you don’t want to change the main model, the best approach is:

• Create a separate staging query that directly reads only recent files (last 1–2 days) using a date filter 
• Apply incremental refresh on that staging table 
• Then append this small “recent data” into your existing model

  This way, you avoid touching your main logic, reduce refresh time, and still get near-incremental behavior.
