incremental refresh policy

Hi prasadpatil020,
Thanks for reaching fabric community will happy to assist.

This usually comes down to how incremental refresh behaves with the Updated Date column.

With a 2-day window, Power BI only refreshes records where the updated date falls in the last 2 days. So:

• If an order was updated yesterday → it gets picked up
• If it was updated 3 days ago → it gets missed (As same as you mentioned)

That’s why things look correct when you use a larger window (like 3 months), but not with 2 days.

• You can try increasing the refresh window to around 7-14 days may give you accurate result
