COUNTROWS: This measure counts the number of rows in the column. In the previous example you learned how to define the GrossMargin column in the Sales table to compute the gross margin amount. The user interface allows you to simply define a new column, but we talk about calculated column to make a distinction between native columns (those read from the data source or evaluated by a query written in Power Query or Power BI) and calculated columns (those created extending a table in the data model). If you need to operate on aggregate values instead of on a row-by-row basis, you must create measures. Depending on the result you want, you can change the type of aggregation. After you select the calculations and fields you want for your quick measure, choose OK. However, not all types of aggregation apply to every numeric datatype.
