Configure incremental refresh and real-time data issue

[TonyChang]

I have tried to explain and setup the configuration incremental refresh and live data for Power BI dataset based on the following link

Configure incremental refresh and real-time data for Power BI datasets - Power BI | Microsoft Learn

Step 1: Create parameters such as RangeStart and RangeEnd as used in the demo. 

Step 2: Refresh data starting at RangeStart and RangeEnd. 

Step 3: Don't see any functionality to define a policy, 

Due to the use of incremental refreshes, the problem always occurs as shown in the figure below.

Hi , @TonyChang 

According to your description, when you configure the incremental refresh , you encounter the error code when you configure the policies for the table .

For your issue, you need to check if you meet the prerequisite for incremental refresh .

(1)You need to connect the data with import mode .

(2)Incremental refresh and real-time data works best for structured, relational data sources like SQL Database . The data source need to support the Query folding .

For more information, you can refer to :
Query folding - Power Query | Microsoft Learn

(3)You need to check the parameter the "RangeStart and RangeEnd" is totalty the same .

Because these two parameters need to be overridden to send requests to the data source during incremental refresh.

(4)You need to check that your Date column is of type Date/Time (not Date); and that the Date column is properly FIltered.And check whether the parameter type is correct "Date/Time".

And you can also see if you meet the prerequisite  for the incremental refresh in this :

And you can also see how to configure the incremental refresh by this viedo:

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!
