How to count values in a report by dates and display them on a chart in weeks

[Anonymous]

Hi,

I have two table Calendar and Purchases.

Calendar:

Date	Week of Year
2020-01-01	1
2020-01-02	1
...	...
2020-12-31	53

Purchases:

ID	Title	Start of purchase	End of purchase
1	Monitors	2020-01-10	2020-02-16
2	Laptops	2020-02-01	2020-03-05

How can I show in the report in which weeks and how much purchases were in progress?

The week in which the purchase was completed shall not be included in that week.

For example, I need to see in report:

Hi  @Anonymous ,

According to your description, I created some data to show:

Here are the steps you can follow：

1. Create calculated column.

Start_week = WEEKNUM('Table'[Start of purchase],1)

End_week = WEEKNUM('Table'[End of purchase],1)

2. Create calculated column.

Number of purchases =
var _time=
CALCULATE(COUNT('Table'[Title]),FILTER('Table','Week Of Year'[Week of Year]>='Table'[Start_week]&&'Week Of Year'[Week of Year]<='Table'[End_week]))

return IF(_time=BLANK(),0,_time)

3. Result.

You can downloaded PBIX file from here.

@ryan_mayu , hi, thank you.

Everything looks good, but if the purchase doesn’t have an end date, the report doesn’t count it. Such a purchase must be in progress (today he is in progress). Can you update the COUNT formula? Thank you.

maybe you can try this

COUNT = 
CALCULATE(COUNTROWS('Table'),FILTER('Table','Table'[start of purchased]<='calendar'[Date]&&('Table'[End of purchased]>='calendar'[Date]&&WEEKNUM('Table'[End of purchased],2)<>'calendar'[week of year]||ISBLANK('Table'[End of purchased]))))

@ryan_mayu That formula doesn't work well. The number of ongoing purchases has increased. Past and future purchases are also displayed. It's not good 😕

@amitchandak , I am not a professional, maybe you can detail the formulas according to my example? Because I can't relate your example to my example.
