Incorrect date format when importing data from Power BI dataset

[dmatliak]

I have a problem with format of my Date field. The field is recognized as date field, it shows values chronologically, but I can not use the date field as hierarchies. The date value is showed in format Month.Day.Year 12:00:00. For example June 30th 2022 would be shown 06.30.22 12:00:00. I can not format the field because I import data via Power BI dataset and this option is not available. Anozher issue is that I can not create any measure where with date functions (for example Year-to-Year comparison or rolling average) where date hierarchies must be used. Anyone can help with this? Thanks a lot.

Hi @dmatliak ,

The date hierarchy will work for you when the below conditions are met:

• Enable automatic date and time
• The table storage mode is Import
• The column data type is date or date/time
• The column isn't the "many" side of a model relationship

For more details, please kindly refer to the blog:

Why there is no date hierarchy - Microsoft Power BI Community

When you connect to Power BI datasets, the default mode is Live connection, which prohibits changing the data type/data format/ create custom hierarchy.

@dmatliak , if you have date table, joined with your date. You should use time intellignece. Using date hierarchy is not a good idea 

Example measures

YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD('Date'[Date],"12/31"))
Last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd('Date'[Date],-1,Year),"12/31"))

Rolling 12 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date ],MAX('Date'[Date ]),-12,MONTH))

Time Intelligence, DATESMTD, DATESQTD, DATESYTD, Week On Week, Week Till Date, Custom Period on Period,

Hi, thanks for you quick reply. But there is a problem with formate of my date field ("leave_date"). It is not formatted properly as date. And I can not format is because I import data from Power BI dataset. See below, I wanted to calculate YTD number of lost clients, but it did not work properly because "leave_date" is not a date field.
