add custom column with year and month concentenated

[bvdm1980]

Hi, i was going through "design a data model in BI" training course, and came at the part where you can add a custom column by adding an applied step, and use dax in custom column to create the MonthYear column

I have my standard calender table created with 5 columns (date/year/month/week of year/day), and added a new step in my applied step, copied the dax code (i typed it as well but just to be sure i copied, so i can't make typo). BUt i cant get it working :

Column = Table.AddColumn(#"Renamed Columns", "Custom", each [Year] & "-" &[Month])

My last 2 applied steps are :

So i click "custom colum" to insert new column, and i see this

then i use the formula:

but then my column shows value "table" in every cell and i can't change the formate of this new column to "date" type...what am i missing in my steps? Tried several times but it just won't work.

Hi @bvdm1980 ,

Try to add a custom column use below formula.

Date.ToText([date],[Format="yyyy-MM"])

Best Regards,

You could try wrapping both the [Year] and [Month] columns in Text.From()
