## 12 Month Sales

Hi

I have created a measure to sum sales over past 12 months, before August 2017

I want the measure to calculate the previous 12 month sales from a date that is selected in a slicer (Dates Table0

Measure = CALCULATE(sum(EOM_STK[Sales]), 'EOM_STK'[perioddate]<=DATE(2017, 08, 1) && 'EOM_STK'[perioddate]>=DATE(2016, 09, 1))

Dates table

Year   Month  FilterDate

2017  01         2017-01-01

2017  02         2017-02-01

etc

if I substitue the dates for the date slicer, I get the error message that the expression contains multiple columns but only a single column can be used in a true/false expression. What am I doing wrong?

You may add FILTER Function to the formula.

Hi,

Apologies for the delay in responding. Filter was the solution, just wasnt sure how to use it.

This was my solution for the sales over 12 months, I had a slicer to select the end period

var curDateStr = CALCULATE ( MIN ( Dates2[FilterDate] ), ALLEXCEPT ( Dates2, Dates2[FilterDate] ) )
var curDate = DATE(LEFT(curDateStr,4),VALUE(MID(curDateStr,6,2)),RIGHT(curDateStr,1))
return
CALCULATE ( SUM ( 'EOM_STK'[SOH] ), FILTER(EOM_STK,
EOM_STK[perioddate]=curDate
))
