How to calculate Average Daily Sales (ADS)

[shahidalaila23]

Hi, 

I'm trying to calculate average daily sales base on sample table above. For now if I calculate using measure, it will calculate only the total day of item sold and not the total month to date. As example, "IK YELLOW COPIER PAPER A4 450S 70G" only have 6 days of sales instead of total of 7 days. The measure calculate average for 6 days and not 7 days. 

below is the ADS formula that I use currently. 

qty ADS = AVERAGEX(VALUES(MASTERCALENDAR[DATE]),[qty total]) 

So the qty ADS should be 3.71 instead of 4.33 which is average for 7 days and not 6 days.

@shahidalaila23 , seem fine at high level,

Try like

qty ADS = AVERAGEX(Summarize(MASTERCALENDAR,MASTERCALENDAR[itemcode], MASTERCALENDAR[DATE],"_1",[qty total]), [_1])

Can you share sample data and sample output in table format?
