SAMEPERIODLASTYEAR()

[procyon82]

I use

Revenue Last Year = CALCULATE(SUM('GA Ecommerce'[Revenue]),SAMEPERIODLASTYEAR('GA Ecommerce'[Date])) to create a column to have my last year's revenue in reference to what is displayed on my graph. That works beautifully!

I also added

Users Last Year = CALCULATE(SUM('GA Traffic'[Pageviews]),SAMEPERIODLASTYEAR('GA Traffic'[Date]))

and it doesn't work. It doesn't give an error, but simply stays blank.

Users Last Year = CALCULATE(SUM('GA Traffic'[Pageviews])

and

SAMEPERIODLASTYEAR('GA Traffic'[Date]))

each work separately though. Does anybody know what's wrong?

This worked for me:

nest two functions: date add and previous month.

I have a table created / have the property configured as a date table.

Importe MismoMes AñoAnt =
CALCULATE(
SUM('MR GOPMX_ViewA'[Importe MN]), DATEADD(PREVIOUSMONTH(DateDim[FullDateAlternateKey]),-11,MONTH))

This worked for me:

nest two funtion: add date and previous month

Importe MismoMes AñoAnt =
CALCULATE(
SUM('MR GOPMX_ViewA'[Importe MN]), DATEADD(PREVIOUSMONTH(DateDim[FullDateAlternateKey]),-11,MONTH))

hi all, I test this solution and worked for me:

workarround:

nest two functions: add date and previous month

Importe MismoMes AñoAnt =
CALCULATE(
SUM('MR GOPMX_ViewA'[Importe MN]), DATEADD(PREVIOUSMONTH(DateDim[FullDateAlternateKey]),-11,MONTH))

Dear friends, unfortunately this function has no solution if there is an error. It is the worst function of Power BI, because it is necessary but only works in an unknown condition and does not work in others. It's a pity that this happens in an excellent solution like Power BI. There will be no solution. If it works, use it if you do not use any other function. That's the truth.

Have you a table date? or have you, at least, one record for any possible date in the two years? If not, the Intelligence functions can't work as expected.

Formula looks right, are you sure there is data for multiple years ?

[procyon82]

Yes, there definitely is data for last year. If I only use:

SAMEPERIODLASTYEAR('GA Traffic'[Date]), it shows me the date for last year. I'm clueless.

Have you a filter on the two dates? Each measure uses a different column date.

[procyon82]

No, I am not using filters

See the lasts words from the description. What is your filter context?

This worked:

Users Last Year = CALCULATE(SUM('GA Traffic'[Users]),SAMEPERIODLASTYEAR('GA Traffic'[Date]), AllExcept('GA Traffic', 'GA Traffic'[Date]))
