You have a table that contains the following data.

To complete the formula, you should drag the option MAX from the list of options and drop it into the first blank space, and then drag the option [Sales] and drop it into the second blank space. The formula will look like this: Option (MAX) Option ([Sales] ). This formula will calculate the maximum value of the sales field for each country. You can use this formula to create a calculated field that will show the highest sales amount for each country in your data source. References:
