Reverse Hybrid table implementation

[Nikhil_Sinha]

Scenario

• The Power BI report should load and store the most recent 13 months of data using Import mode, ensuring fast performance and responsiveness for commonly accessed data.
• The report should also allow users to select dates older than the last 13 months via a slicer. When a user selects such an older date, the report should dynamically fetch the relevant data using Direct Query mode, so users can access historical data on demand without impacting the performance of the main report.
• The data model should seamlessly integrate both Import and Direct Query modes, so users experience a unified view regardless of the data source.
• The slicer should display all available dates, but the underlying logic should ensure:
• Dates within the last 13 months are served from Import mode.
• Dates older than 13 months are served from Direct Query mode.

Hey!  Yes... this is doable, but not with a single table switching modes automatically. In Power BI you achieve this using a composite model with Hybrid Tables (Incremental Refresh + Real-time). 

Recommended approach:

• Use one fact table.

• Configure Incremental Refresh.

• Store the last 13 months in Import.

• Keep older data as DirectQuery (real-time partition).

• Use a normal Date slicer that shows all dates.

Power BI will automatically route queries:

• Last 13 months → Import (fast)

• Older dates → DirectQuery (on demand)

Also important to remember: DirectQuery should mainly be used when you truly need real-time or near real-time data. If your dataset refreshes daily (or less frequently), Import mode is usually the better choice for performance, stability, and lower source-system load.

Hope that help,

Hi @Nikhil_Sinha 

I kinda feel like you are looking something similar to incremental refresh , please check if this helps : https://learn.microsoft.com/en-us/power-bi/connect-data/incremental-refresh-overview
