Get % difference in sales with promotion of product

Hi ,

 

Looking to determine the effect of certain events on sales e.g. promotion of product.

 

e.g. have sales table and rows which flagged if sale occured during event e.g promotion of a product 

customer

, product

, sales_qty

, sale_date

, 'Promotion active_flag'

 

example data

joe bloggs

, beans

,10

,'01-jun-2020'

,'Promotion Active'

 

joe bloggs

, beans

,2

,'01-MAY-2020'

'No promotion'

 

Want to see sales of these 

 

User can select sales date e.g. if select 01-jun-2020' onwards t0 '30-jun-2020', have below

CALCULATE(AVERAGE('Sales'[Sales Qty]),'Epos Sales'[Event Descriptor]="Promotion Active")

However, if say user selects as partciular date, only want the avarge in formula below to take into account the corresponding day of week.  How can we best achieve this?

 

CALCULATE(AVERAGE(' Sales'[Sales Qty]),'Sales'[Event Descriptor]="No Promotion Active",ALL('Sales'[Sales Date]))
 
Thanks

Hi,

 
Thanks for reply.
 
 
What means is that user can select a date via a slicer, which is all dates after promotion started.
 
If say they select a date which is a wednesday, wish to compare the sales on this date to an average of wed sales before the prmotion started 
 
Believe have managed to do this va below but may be better way?
 
 
 
SWITCH(weekday(max('Sales'[Sales Date]),1)-1
,0,CALCULATE(AVERAGE(' Sales'[Sales Qty]),ALL(' Sales'[Sales Date]),' Sales'[ Descriptor]="Before promotion",'Calendar'[Day of Week]=0)
,1,CALCULATE(AVERAGE(' Sales'[Sales Qty]),ALL(' Sales'[Sales Date]),' Sales'[ Descriptor]="Before promotion",'Calendar'[Day of Week]=1)
,2,CALCULATE(AVERAGE(' Sales'[Sales Qty]),ALL(' Sales'[Sales Date]),' Sales'[ Descriptor]="Before promotion",'Calendar'[Day of Week]=2)
,3,CALCULATE(AVERAGE(' Sales'[Sales Qty]),ALL(' Sales'[Sales Date]),' Sales'[ Descriptor]="Before promotion",'Calendar'[Day of Week]=3)
,4,CALCULATE(AVERAGE(' Sales'[Sales Qty]),ALL(' Sales'[Sales Date]),' Sales'[ Descriptor]="Before promotion",'Calendar'[Day of Week]=4)
,5,CALCULATE(AVERAGE(' Sales'[Sales Qty]),ALL(' Sales'[Sales Date]),' Sales'[ Descriptor]="Before promotion",'Calendar'[Day of Week]=5)
,6,CALCULATE(AVERAGE(' Sales'[Sales Qty]),ALL(' Sales'[Sales Date]),' Sales'[ Descriptor]="Before promotion",'Calendar'[Day of Week]=6)
)

Use this measure:

 

 

Sales Before Promo Avg same Week Day = 
VAR _WeekDay =  WEEKDAY(SELECTEDVALUE(Sales[Sales Date]))
RETURN
CALCULATE(
    AVERAGE(Sales[Sales Qty]),
    Sales[Descriptor]="Before promotion",
    FILTER(ALL(Sales),WEEKDAY(Sales[Sales Date])=_WeekDay)
)
