Unable to Load Data - Row Limit?

I have a SQL direct connection to my DB in Azure and I am wanting to report data from a view which pulls the records from a couple of tables over the last 365 days. In my view, I have calculated a 'Success Rate' column, which simply divides 2 columns and multiplies the result by 100 (to give it a percentage view, if you like). There are around 900 rows.


Now, when I try to pull the 'success' column into a report in PowerBi, I get;


Couldn't Load the Data for this Visual

Please try again later


I then an identical view to pull records from the last 30 days and it ran fine. There are 74 rows.


What is the limit on the number of rows Power BI is able to work with??

Well, I do not know that we have a spefic row limit. Nevertheless, the files should not exceed 250 MB, which usually equals to several million rows of data. I have also used that data for visuals and tables. Also, for different backends I have not experienced something similar to what you have described.


Where have you created the "success rate" column? In the backend or in Power BI?


DirectQuery does not work with measures and calc. columns in Power BI so far. I guess we will see some improvements there soon, as DirectQuery is the go-to-solution.


// What i recommend: Use other visuals.
