Column that returns prior year value

[Anonymous]

Hi All, 

I am trying to add a column in to my table model that returns Prior Year amounts. Please see attached. For some reason my current formula is not working. Does anyone know how to solve for this issue?

Thanks,

Hi @Anonymous ,

Your formula is correct, while the SAMEPERIODLASTYEAR function should be used in measure instead of calculated column, see the link: https://docs.microsoft.com/en-us/dax/sameperiodlastyear-function-dax.

If you need to get the prior year amounts using a calculated column, you may create columns like DAX below.

Year= 'HFM Extract lc' [Date]
 
Prior year amounts= CALCULATE(SUM('HFM Extract lc' [Amount]), FILTER('HFM Extract lc', 'HFM Extract lc'[Year]=EARLIER('HFM Extract lc'[Year])-1))

Hi @v-xicai ,

When I plug in that formula no values are returned. Am I doing this correctly?

Hi @Anonymous 

Why don't you want to use a measure?

If the row context is transformed into a filter context by calculate, is filtering over each column?
Does the line from the previous year only differ in the date? or also e.g. in FX rate etc.

I am trying to calculate organic growth for a region and am not able to do this for a measure because it adds the local currencies of the countries together before multiplying by the FX rates to convert back to USD. Because of this I need to translate all the accounts for each country back to USD using the prior year FX rates and then sum the results, so that currencies aren't mixed. 

i.e. - I need  (Country 1 $'s*  PY FX rate) + (Country 2 $'s *PY FX rate) = Organic Dollars

The measure calculates the following  (Country 1 $'s +Country 2 $'s) *(Country 1 PY FX rate+Country 2 PY FX rate) = Incorrect

Hi,

that's the use case for SUMX.
Look at this.

Hi @Anonymous ,

you have to create a Measure.

Look at this.

Remember, you compute the ratio of the sums, not the sum of the ratio.

This one should be created as measure.

I use following

YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(('Date'[Date])))

Last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd('Date'[Date],-1,Year)))
Last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(ENDOFYEAR(dateadd('Date'[Date],-1,Year))))
last year measure =CALCULATE(SUM(Sales[Sales Amount]),(dateadd('Date'[Date],-1,Year)))
