Power BI Concatenating two measures together under one column header for a table display

Another requirement came through for a table that showed the current month figures against last months figures,

However, to save space the two values were in the same column, last month contained in a ()

So part one was to create the date time intelligence for last month,

And then to attempt to concatenate the two figures just for the table

Time intelligence to see this time last month

There are various ways of doing this

Prev Month At Risk = CALCULATE([At Risk],PARALLELPERIOD('Dim'[Date], -1,MONTH))

Here we use CALCULATE to evaluate the SUM of At Risk (created in a base measure already) in a modified filter context. Which is PARALLELPERIOD using the date from the Date Dim.

PARALLELPERIOD takes the current set of dates (For us its month and year) and shifts the first and last date in the period specified a number of intervals. -1 takes us back a month.

This is the chosen method but you can also use

CALCULATE([At Risk],DATEADD(‘DimDate'[Date],-1,MONTH))
DATEADD returns a table that contains dates shifted forwards or backwards in time the number of intervals from the date in the current context. Again we are sing Month and Year in the current Context.

Returns a table that contains a column of dates, shifted either forward or backward in time by the specified number of intervals from the dates in the current context

PREVIOUSMONTH('Dim Report Snapshot Date'[Date]))

PREVIOUSMONTH returns all dates from the previous month using the first date in your context. As we are using month, our first date is 0103 so it goes back to 0102


Returns a table (Its a table expression) Returns a single column of date time values from the same period in your current context from last year, SAMEPERIODLAST Year can only go back a year.

Concatenate current month and Last Month into one single value

This is for a table only. Not to be used for Proper analytics.

So first we need to convert the number into a string.

And then we can concatenate. The following was used

At Risk =
VAR varMeasure = CONVERT([At Risk],STRING)

VAR varPrev = CONVERT([At Risk],STRING)

VAR varConcata = CONCATENATE(varMeasure,”(“)

VAR varConcatb = CONCATENATE(varPrev,”)”)



There will be lots of other ways to do this but I decided on the following
Creating Variables to hold:

  • The measure converted to a string
  • The previous (Month) measure converted to a string
  • CONCATENATE (You can only concatenate two things using this method) so The measure was concatenated with (
  • CONCATENATE, Doing the second part of the concatenation. The previous Month String value with )
  • Finally we return a Concatenation of a and B so make a string value we can use for the table.

To CONCATENATE more that two columns you can use

Column D = [column A] & " - " & [column B] & " - " & [column B]

So were we have 5 measures and a total. To view them in the table under one column header we have concatenated them together.
