Rolling DateTime Calulation

[Jan1984]

Hello All,

I am Receiving a daily rolling 10 Days Extract every day, where I need to modify the provided Date Column.

Therefore I created an example Dataset with only the Date Column(File -->https://we.tl/t-8qG67CEYcQ) for testing purposes.

Below you find the criteria’s I would need…

Dates within the Extract…

• Todays Extract would be - From MinDateTime(02 Mar 2022 00:45) to MaxDateTime(11 Mar 2022 08:20)
• Tomorrows Extract would be - From MinDate(03 Mar 2022 XX:XX) to MaxDate(12 Mar 2022 XX:XX)

Required date changes in an Extra Calculated Column should be…

1. Dates > MaxDate 11 Mar 07:00 == Blank or NA

1. 11/02 07:00 – 10/02 06:59:59  == 11/02
2. 10/02 07:00 – 09/02 06:59:59  == 10/02
3. 09/02 07:00 – 08/02 06:59:59  == 09/02
4. 08/02 07:00 – 07/02 06:59:59  == 08/02
5. 07/02 07:00 – 06/02 06:59:59  == 07/02
6. 06/02 07:00 – 05/02 06:59:59  == 06/02
7. 05/02 07:00 – 04/02 06:59:59  == 05/02
8. 04/02 07:00 – 03/02 06:59:59  == 04/02
9. 03/02 07:00 – 02/02 06:59:59  == 03/02

1. Dates < MinDate  02 Mar 07:00 == Blank or NA

Thanks in advance for your Support

Have a nice Day

Best Regards

Jan

@Jan1984 Maybe:

let
    Source = fnDateTable(#date(2020,1,1), #date(2022,12,31)),
    #"Filtered Rows" = Table.SelectRows(Source, each Date.IsInPreviousNDays([Date], 10))
in
    #"Filtered Rows"

Hello,

Thanks a lot for you reply, unfortuanatly the provided idea is not exactly what i am looking for because my rolling every day rawdata will show the prev. 10 days anyway so your filtering solution would be obsolete.

I rather try to create an additional Date column where i am grouping the existing Dates based on the above provided criterias.
