PL-300 Exam – Practice 14 Welcome to your PL-300 Exam - Practice 14 Question 1 You create a quick measure Sales Amount MTD to display the Month-to-date total of Sales Amount values using Order Date (see the below representation). In the visual, the Order Date in the Values well uses the Power BI auto date/time generated hierarchy (Year, Quarter, Month, and Day). You have to replace the Year, Quarter, Month & Day columns with a single Date column without breaking the visual.Which of the following solutions would you use? From the Order Date hierarchy in the Values well, you use the context menu to switch from the date hierarchy to the date column (Order Date). Turn off the auto date/time option for the current .pbix file. Create a separate Date table and slice the quick measure using the date column from the Date table. Create a quick measure using the date column in the Date table.
