Click Insert to insert the field and the function into the expression editor.Tip: You can open the online help with the full description of how to use the current function by double-clicking the function name in the expression editor and pressing Ctrl+H on the keyboard. This feature becomes available after having entered the first parenthesis of the expression after the function name, and only when using a computer with a keyboard.
Click Apply to close the Add expression dialog.
Now you need to add some descriptive data for the measure.
