Dividing Values to a Constant Interval Date

[Anonymous]

Hello,

I'm working on a table which has these columns:

- Date (1st March 2020 to 21st May 2020)

- Amount

- Name of Product

I want to track the changes in the dates. The logic is: 1st March is Sunday so starting from 8st March, I want all sunday days (8, 15, 22 March or 21, 28 April, etc) to be divided by 1st of march value.

Ex:

1 Mar: 100

8 Mar: 125

15 Mar: 110

then I want to have on

8 Mar: 1.25

15 Mar 1.1 etc.

How can I do that?

Thanks.

Hi @Anonymous ,

I created some sample data on my desktop, and I hope the result is what you want.

Column = VAR TEST = CALCULATE(MIN('Table'[DATE]),ALL('Table'))
          RETURN  IF('Table'[DATE] = TEST,0,IF(WEEKDAY('Table'[DATE]) = WEEKDAY(TEST),1,2))

Measure 8 = DIVIDE(CALCULATE(SUM('Table'[VALUE]),'Table'[Column] = 1),CALCULATE(SUM('Table'[VALUE]),FILTER(ALL('Table'[DATE],'Table'[Column]),'Table'[Column] = 0)))

Please try.

Hello,

@AiolosZhao @v-lionel-msft 

Both answers didn't work Let me clarify myself I think I didn't express myself well.

My table is on the link as excel file ( https://bit.ly/2ZZbsCT ). the first week is my control week (1-7 march) and starting from 8th Mar, I want all sundays (8, 15, 22 Mar, etc) to be divided by 1st Mar, all thursdays (12, 19, 26 Mar, etc) to be divided by 5th March, etc.

By the way, I'm showing one of the product code as an ex. There are a lot more.

Hi @Anonymous ,

Please refer to my .pbix file.

Measure 3 = 
IF(
    SELECTEDVALUE(Sheet2[Weekday]) = SELECTEDVALUE('Table'[_Weekday]) && SELECTEDVALUE(Sheet2[Date]) > DATE(2020, 3, 7),
    DIVIDE( SELECTEDVALUE(Sheet2[Amount]), SELECTEDVALUE('Table'[_Amount] ) )
)

Hi @Anonymous ,

Try to do like this.

Measure 2 = 
VAR x = 
CALCULATE(
    MAX(Sheet2[Amount]),
    FILTER(
        ALL(Sheet2),
        Sheet2[Date] = DATE(2020, 3, 1)
    )
)
VAR y = 
CALCULATE(
    MAX(Sheet2[Amount]),
    FILTER(
        Sheet2,
        Sheet2[Weekday] = 1
    )
)
RETURN
DIVIDE(
    y, x, BLANK()
)
