table. Then we use the FILTER function to include only those rows where the count of distinct PersonNames is greater than 10, and finally use the COUNTROWS function to count the number of distinct States that meet this condition. The formula uses a filter expression to get only the rows in the Product table that meet the condition, ProductSubCategory = "Caps", and then counts the rows in the resulting table that have a list price. Hevo loads the data onto the desired Data Warehouse/destination in real-time and enriches the data and transforms it into an analysis-ready form without having to write a single line of code.

For efficient aggregations over physical tables in the model, consider using SUMMARIZECOLUMNS or SUMMARIZE function. The COUNTX function takes two arguments. The table containing the rows to be counted. The GROUPBY function is similar to the SUMMARIZE function. GROUPBY permits a new function, CURRENTGROUP (), to be used inside aggregation functions in the extension columns that it adds. To explain this scenario, I am taking an example data.
