Error free measure from Power BI Desktop returns an error after publishing

[Daniel1]

Hi all,

I created my first dashboard in Power BI desktop and everything was working fine. After publishing the dashboard to power BI online one of my measures returns an error.

Measure: YTD2017 = CALCULATE(SUM(APEWeekly[GAP CZK]); DATESBETWEEN(DateDimension[DateKey];"27.12.2016";LASTDATE(DateDimension[DateKey])))

The error message is: MdxScript(Model) (4, 99) Calculation error in measure 'APEWeekly'[YTD2017]: Cannot convert value '27.12.2016' of type Text to type Date.

I understand that there is a problem with the date format for 27th December 2016. But I have no idea why as there is no error and the measure works in the Power BI desktop.

For clarification, the measure calculates YTD sales and I can't use the YTD function as our year starts on 27th of December 2016.

Thank you for your help.

Daniel

I don't think it has anything to do with that specific date, but with the way you're entering it. Instead of "27.12.2016" try using the DATE() function.

Perfect, thank you very much! Now it works fine.

I hardly ever trust localized date order to work properly in Power BI or Excel. And I'm in the US. If it's at all possible to use a function to make the month and day explicit in a date, I always recommend using that option instead of letting the program try to parse a whole date.
