TOTALQTD: This function calculates a cumulative total for a measure from the beginning of the quarter (or any specified starting date) to the given date. SAMEPERIODLASTYEAR: This function allows you to retrieve data for the same time period in the previous year. It is useful for year-over-year comparisons. DATEADD: This function allows you to add or subtract a specific time period from a given date.
