I have created RLS in Powerbi and have provided restricted access to users. Users are sometimes( not regularly) getting error as 'couldn't load the data for this visual'. What might be the reason and how to rectify this.

Hello, ChayanFloridaBlue 

The intermittent error ‘couldn’t load the data for this visual’ in Power BI when using Row-Level Security (RLS) could be due to several reasons. Here are some potential causes and solutions:

Data Refresh Issues: Ensure that the dataset is refreshing properly. If there’s a scheduled refresh, check if it’s completing successfully.
Complex Measures or Calculations: If you have complex measures, they might be causing the issue. Simplify the measures or break them down into smaller parts.
Date Format in Measures: Incorrect date formats in DAX formulas can cause errors. Ensure that date formats are consistent and correct.
DirectQuery Performance: If you’re using DirectQuery, the error might occur due to large volumes of data. Consider filtering or aggregating data before loading it into Power BI.
RLS Configuration: Verify that RLS is configured correctly and that users have the appropriate roles assigned to them. Admins and dataset owners can see all records even if they don’t have RLS roles, which might not be the case for other users.
Power Query Issues: Check all queries in Power Query to ensure they load without authentication errors. Reconfigure connections and credentials if necessary.

I hope this step is helpful to you.
