Some advantages of model measures are that you can name them whatever you want, making them more identifiable. The SELECTEDVALUE function did not introduce a new feature it just simplifies the syntax required in common coding patterns, as you will see in a few of the possible uses presented after the description of the SELECTEDVALUE syntax.

This might seem strange if you are accustomed to SQL-computed columns not persisted which are computed at query time and do not use memory. Measures give you the power to get the insights you want from your data. The relationship is defined by naming, as arguments, the two columns that serve as endpoints. The chart now uses two measures: SalesAmount, which Power BI summed automatically, and the Net Sales measure, which you manually created. For example, if you have to create a measure based on the result of a product made row-by-row, you can define a calculated column and then a measure as follows: Or you can just use a single measure that evaluates the same expression of the calculated column row-by-row within the iteration of a table.
