Date Hierarchy stopped working

[hrmeehan]

I have been running reports for about 6 months now and everything is fine. 3 months ago, all my reports suddenly "broke" and now the dates are separating out by days instead of summing into month/year. I can use the date slicer, but it sums all the years into the month (January contains totals of 2015-2018). I want it to show a trend of months over years. I know this is probably a really stupid question, but I cannot figure out what happened.

Hi @hrmeehan,

Did you add a date column onto X-axis of a chart? If so, you can click the drill down option on the top left to switch the aggregation level (Day, Month or Year).

It turned out to be something simple. I did format the column as a date, but I had to set it to "Start of month" in order for it to roll the days into the month. Thanks!
