Last week's sales by product

[Anonymous]

Hi Community! 

I'm aiming to calculate last week's sales for each product. 

My primary sales table has four column: 

Date

Product ID

Date

Quantity Sold

I have tried the following formula, but it's yielding an aggregate result that does not disaggregate by product. 

CALCULATE(SUMX(Sales,Sales[amount]),

FILTER(ALL('Calendar'),

'Calendar'[week_num] = SELECTEDVALUE('Calendar'[week_num]) - 1 &&

'Calendar'[year] = SELECTEDVALUE('Calendar'[year])))

Any help to get the disaggregated results by product would be super helpful!

Hello Community,

I would like to ask for help regarding my concern. I am trying to get the total of each product type through measure and comparing it from last week sold and this week sold but I can only get the total sold of all products when I am filtering my product type. Is there a way to get the total on each product type? Please see below my measures.

Sold Last Week = CALCULATE(SUM('Product Database'[Total Sold]),FILTER(ALL('Product Database'),'Product Database'[Week Rank]=MAX('Product Database'[Week Rank])-1))

Sold This Week = CALCULATE(SUM('Product Database'[Total Sold]),FILTER(ALL('Product Database'),'Product Database'[Week Rank]=MAX('Product Database'[Week Rank])))

Sold Weekly by % = ([Sold This Week]-[Sold Last Week])/'Product Database'[Sold Last Week]

Thank you for your help on this matter.

Create a rank on the week start/end date of week no (YYYYWW) and then use that. Date is my Calendar table here

Week Start date = DATEADD('Date'[Date],-1*WEEKDAY('Date'[Date])+1,DAY)
Week End date = DATEADD('Date'[Date],7-1*WEEKDAY('Date'[Date]),DAY)
Week Num = if('Date'[Week Number] <10 ,'Date'[Year]*10 & 'Date'[Week Number], FORMAT('Date'[Date],"YYYYWW") )

Week Rank = RANKX('Date','Date'[Week Start date],,ASC,Dense)

Measure = CALCULATE([AH], all('Date'),filter('Date','Date'[Week Rank]=max('Date'[Week Rank])-1))

this Week using rank = CALCULATE(sum(Sales[Amount]),all('Date'),filter('Date','Date'[Week Rank]=max('Date'[Week Rank])))

Last Week using rank = CALCULATE(sum(Sales[Amount]),all('Date'),filter('Date','Date'[Week Rank]=max('Date'[Week Rank])-1))

Hi! Thank you for the response, but I'm looking for a simpler solution. Right now, the following formula works but only with one of the conditions (currYear or currWeek), not both. Do you know what I may be doing wrong here?

Diff =

VAR currYear = MAX ( 'Calendar'[year] )

VAR currWeek = MAX( 'Calendar'[week_num] )

RETURN

CALCULATE (

SUM ( Sales[amount] ),

FILTER ( ALLSELECTED('Calendar'),'Calendar'[year] = currYear && 'Calendar'[week_num] = currWeek),

VALUES ( Sales[product_id] )

)

Try

Prev Week =
var _year =MAX ( 'Calendar','Calendar'[year] )
var _date = date(_year-1,12,31)
var _maxPweek = weekno(_date)
VAR _maxWeek1 = MAXX('Calendar', 'Calendar'[week_num] )
VAR _maxWeek = if([_maxWeek1]=1 ,_maxPweek, _maxWeek1-1
var _cYear = MAXX ( 'Calendar','Calendar'[year] )
Var _maxYear = if([_maxWeek1]=1,_cYear-1,_cYear)
return 
CALCULATE (
SUM ( Sales[amount] ),
FILTER ( all('Calendar'),'Calendar'[year] = _maxYear && 'Calendar'[week_num] = _maxWeek),
)


This Week =
VAR _maxWeek = MAXX('Calendar', 'Calendar'[week_num] )
var _maxYear = MAXX ( 'Calendar','Calendar'[year] )
return 
CALCULATE (
SUM ( Sales[amount] ),
FILTER ( all('Calendar'),'Calendar'[year] = _maxYear && 'Calendar'[week_num] = _maxWeek),
)
