Power BI - Measures and Quick Measures
Measures and Quick Measures are a very powerful tool in Power BI. What are Measures? Sometimes your data doesn't include everything you need to answer questions.
You use DAX formulas to create a measure field that you can then use in the report or Data view. Examples of measures are sums, averages, minimum or maximum values and counts. For more advanced calculations, you can create yourself using DAX. The calculated results of measures are always changing in response to your interactions.
Measures you create will show in the field list with a calculator icon next to the field.
Quick measures are pre-built measures. You do not have to write your own DAX syntax. You are prompted to input data into dialog boxes, the results are then presented for you to use in your report. You can also see the DAX created which will help you learn DAX.
There are 5 distinct groups of quick measures calculation types Aggregate per category, Filters, Time intelligence, Totals and Mathematical operations text.
To create a quick measure right-click on a field (any field) and select New quick measure. Then select the calculation you want to use and the fields against which you want the calculation to run.
