Hi , @Niraj_vora0106 

According to your description, you want to create a date table. And now you use the calendarauto() function.

For this , i do not recommend you to use the calendarauto() function. Because it auto-create a date table from all the date type column from your date source, it will affect performance.

I recommand you to use calendar() function to create a date table , like this:

Calendar = ADDCOLUMNS( 
CALENDAR(FIRSTDATE('Table'[Date]),LASTDATE('Table'[Date])),
"Year", YEAR ( [Date] ),
"Quarter", ROUNDUP(MONTH([Date])/3,0),
"Month", MONTH([Date]),
"Week", weeknum([Date]),
"Year_Quarter", year([date]) & "Q" & ROUNDUP(MONTH([Date])/3,0),
"Year_Month", year([Date]) * 100 + MONTH([Date]),
"Yeer_WeekNum", year([Date]) * 100 + weeknum([Date]),
"Weekday", WEEKDAY([Date],2) 
)

 

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI! 

 

Best Regards,

You can create custom Date tables with M (query editor) or DAX, and there are many good examples out there to start with. Here is one.

Yes M-Query is also another option.

Hi @Niraj_vora0106,

The CALENDARAUTO() function basically displays all dates starting from the year start of the minimum date in the model and ending with the fiscal year end date of the  maximum date in the column.

 

To solve this, try to find out if any table in the data model is having dates with wierd year

Hi,

 

You can define a Min Year and a Max Year to your date table.


Please refer to the very good instructions from SQLBI :
