Hello we have a dataset whereby the rows contained a datetime field.But because of the high cardinality we splitted this in a date and a time field.We have to refresh this data on a daily basis. But for that we need a datetime field.But then we create again the isssue of the high cardinality.In the table we also have a day-key. Do you always need a datetime field to do a refresh?How to solve this problem? RegardsRon

Yes. That was your goal, to keep the cardinality low, right?

Your RangeStart and RangeEnd parameters need to be DateTime, and they need to be used in the Power Query filter for the query/table that you want to implement incremental refresh for.

But it doesn't really matter what they compare to. So you could write a filter that says

DateValue+TimeValue > RangeStart and DateValue+TimeValue <= RangeEnd

  Ok, so you then keep the date and time field as separate fields? Also when comparing to RangeStart and RangeEnd>

lbendlin one more question. It is not possible to use just a Date field (so not a Datetime field) for RangeStart and RangeEnd?

  Sure. All you need is to cast your date field as datetime during the comparison (basically pegging the time at midnight)

    Hmm, how does the casting work lbendlin ?
