Arguments
measure
The argument must be a field. Null values are omitted from the results. Literal values don't work.
dateTime
The Date dimension over which you're computing PeriodToDate aggregations.
period
The time period across which you're computing the computation. Granularity of YEAR means YearToDate computation, Quarter means QuarterToDate, and so on. Valid granularities include YEAR, QUARTER, MONTH, WEEK, DAY, HOUR, MINUTE, and SECONDS.
endDate
(Optional) The date dimension that you're ending computing periodToDate aggregations. It defaults to now() if omitted.
Example
The following example calculates the week-to-date minimum fare amount per payment type, for the week of 06-30-21. For simplicity in the example, we filtered out only a single payment. 06-30-21 is Wednesday. Insights begins the week on Sundays. In our example, that is 06-27-21.
