Incremental Refresh

Hello Guys,

I have a power bi dataset which consists of 60 months of data and Incremental Refresh is enabled with a range of 60 months (detect data change enabled on Modified date). I have a pro license and I publish the dataset, the full refresh takes around 2 hrs and then the scheduled refresh also takes around 1.5 hours to complete. So are there any options by which I can reduce the time of scheduled refresh?

    you will have diferent ways to see this,

    1) 60 month isnt a little to big window to refresh for a indremental refresh? example does tha data of the month number 60? 59, ..... 24? change like actually have a data change over time ? could be u pulling a lot of data from the refresh with that set up. 

    2) use tools as dax editor, tabular, etc to do performance check on all your model, best practice, dax peformarce, relantionship (many to many with both direction relantionship affect greatly performance when used incorrectly, unneeded columns, un used measures. un used tables, etc.

    Hi, Angith_Nair 

     

    What is incremental refresh of your data source? You need to see if your data source supports query folding.

    Query folding - Power Query | Microsoft Docs

     

    If the data source does not support query folding. Which means that it has to load all the data first, and then determine which data to load incrementally. In doing it in this manner it will not be any quicker using incremental refreshing.

     

    For reference:
