I have data sorted by date in 15 minute increments. Date and time are separate fields. Time increments are 00:00 - 00:14, 00:15-00:29, etc., all the way to 23:45 - 23:59.
Is it possible to combine these increments into hours, so that the first four increments of the day will be combined into 00:00 - 00:59? Do I use the load statement for that?
I think you could use class(minutes(YourTimeField), 15) or ceil(minutes(YourTimeField) / 15) to group the minutes and used further fields like hour(YourTimeField). I suggest this not to make within the fact-table (especially if they is larger) else to use master-calendar and master-time-table, see: How to use - Master-Calendar and Date-Values.
