## Previous period measure (no date)

Hi community,

I would like to create one simple measure for previous period revenue without using "date" field. So I have created an index for each update I will do (every week). I will use a slicer on the index/week, so if i select week 2, prior should show week 1 figures.

I have several rows so I am using the following formula to calculate "Sales Period" :

Sales Period = SUMX(FILTER(Sheet1, MAX(Sheet1[index])),Sheet1[sales])

How can we calculate "Sales Prior" ? I've tried the following DAX but it's not working :S

Sales Prior = SUMX(FILTER(Sheet1, MAX(Sheet1[index])-1),Sheet1[sales])

 Index Week Sales Sales Period Sales Prior 1 week 1 50 1 week 1 100 2 week 2 20 20 150 3 week 3 30 30 20

Hi @EddyBA

You need to create an independent Week table,

``weekslicer = VALUES('Table'[Index])`` then create the measures bellow,

``test1 = CALCULATE(SUM('Table'[Sales]),ALLEXCEPT('Table','Table'[Week]))``
``````test2 =
VAR _week =
SELECTEDVALUE ( weekslicer[Index] ) - 1
VAR _valuePrior =
CALCULATE (
SUM ( 'Table'[Sales] ),
FILTER ( ALL ( 'Table' ), 'Table'[Index] = _week )
)
RETURN
IF (
MIN ( 'Table'[Index] ) = SELECTEDVALUE ( weekslicer[Index] ),
_valuePrior,
BLANK ()
)``````  Best Regards,

Hi,

Have a look at EARLIER function:

Thank you ValtteriN,

I have already tried this function but unfortunately it's not working.  Super User

Hi,

Another option that comes to my mind besides utilizing EARLIER is separating weeknum into its own column and using that in the calculation. e.g.

[earlierWeekSales] =
var _week = MAX(calendar[weeknum])
var _latestweek = CALCULATE(MAX(Table[weeknum]),ALL(calendar),table[weeknum]<_week)
return
CALCULATE(SUM(table[value]),ALL(calendar),table[weeknum]=_latestweek)

Edit: you might need to add years to the calculate, but the basic logic is the same
