DAX Error: Creating new Date Table

[A-IT]

I'm attempting to write a DAX that will create a new Date Table. I tried to use the following:

Date =
ADDCOLUMNS (
CALENDAR (DATE(2018,1,1), DATE(2024,12,31)),
DateAsInteger = FORMAT( [Date], "YYYYMMDD"),
Year = YEAR( [Date]),
Month Number = FORMAT( [Date], "MM"),
Year/Month Number = FORMAT( [Date], "YYYY/MM"),
Year/Month Short = FORMAT( [Date], "YYYY,mmm"),
Month Short = FORMAT( [Date], "mmm"),
Month Long = FORMAT([Date],"mmmm"),
Day # = WEEKDAY( [Date]),
Day of Week = FORMAT([Date],"dddd"),
Quarter = "Q" & FORMAT([Date],"Q"),
Year Quarter = FORMAT([Date],"YYYY") & "/Q" & FORMAT([Date],"Q"),
Week of Year = WEEKNUM('Date Table'[Date] )

The DAX works when I put them into the individual columns. The issue is when I try to create the table in one function.

Hi @A-IT 

Your dax may have someting wrong in the format of Addcolumn function.

It should be like addcolumns(table,"Name1","Expression1","Name2","Expression2"...)

For more info to Addcolumn function: Addcolumn

I update your dax and build a calculated table as below.

Date = 
ADDCOLUMNS (
    CALENDAR ( DATE ( 2018, 1, 1 ), DATE ( 2024, 12, 31 ) ),
    "DateAsInteger", FORMAT ( [Date], "YYYYMMDD" ),
    "Year", YEAR ( [Date] ),
    "Month Number", FORMAT ( [Date], "MM" ),
    "Year/Month Number", FORMAT ( [Date], "YYYY/MM" ),
    "Year/Month Short", FORMAT ( [Date], "YYYY,mmm" ),
    "Month Short", FORMAT ( [Date], "mmm" ),
    "Month Long", FORMAT ( [Date], "mmmm" ),
    "Day #", WEEKDAY ( [Date] ),
    "Day of Week", FORMAT ( [Date], "dddd" ),
    "Quarter", "Q" & FORMAT ( [Date], "Q" ),
    "Year Quarter",
        FORMAT ( [Date], "YYYY" ) & "/Q"
            & FORMAT ( [Date], "Q" ),
    "Week of Year", WEEKNUM ( [Date] )
)

Result:

Thank you! This worked great. I need to go look at the two side by side and determine where I made the error. It's awesome that I can create the date table from scratch in seconds now!

I found the error when looking at them side by side. I wrote the DAX as:

'Month Number' = FORMAT( [Date], "MM"). It should not use "=" in the syntax. It should be:
"Month Number", FORMAT ( [Date], "MM" ),

I'm learning, thank you!

Hi @A-IT 

Addcolumn functions works on calculate column ....If you want a table the use the below function

//

Date =

VAR MinYear = YEAR ( MIN ( Sales[Order Date] ) )

VAR MaxYear = YEAR ( MAX ( Sales[Order Date] ) )

RETURN

ADDCOLUMNS (

    FILTER (

        CALENDARAUTO( ),

        AND ( YEAR ( [Date] ) >= MinYear, YEAR ( [Date] ) <= MaxYear )

    ),

    "Calendar Year", "CY " & YEAR ( [Date] ),

    "Month Name", FORMAT ( [Date], "mmmm" ),

    "Month Number", MONTH ( [Date] )

)
Note:Sales[Order Date]--> change this based on your table which has date column
