Get Average of the last 7 days starting on Tuesday

Good afternoon everyone!

I hope you can help me.

I need PowerBI to show me the average of the last 7 days starting on Tuesday.

From Tuesday the price changes are made.

I could not find any formula that takes me the average of the last 7 days starting from Tuesday

Example

In return a table or Matrix with a row showing a result

Search Forums, Internet Videos, I asked for help from other colleagues but couldn't get it.

I hope you will help me,

Best regards!

Hi,

Please check the below picture and the attached pbix file.

I tried to create a sample pbix file like below.

One of ways to achieve this is to create a proper calendar table like the attached pbix file, that DayOfWeek number starts from Tuesday (1) and ends on Monday (7).

I hope the below sample can provide some ideas on how to create a solution for your datamodel.

Avg last 7 days start from Tue: =
AVERAGEX (
    ADDCOLUMNS (
        FILTER (
            ALL ( 'Calendar' ),
            'Calendar'[End of Week] = MAX ( 'Calendar'[End of Week] )
                && 'Calendar'[Day of Week] <= MAX ( 'Calendar'[Day of Week] )
        ),
        "@qty", [Qty measure:]
    ),
    [@qty]
)

Hi,

Thank you for your feedback.

In the formula, @ has no meaning. It is just my habit that I learned from some other experts. When I try to create a column in a virtual table inside DAX formula, I usually name it with @, and the reason is not to be confused by other existing measures or other existing columns (Other existing measures come with table name, so the main purpose is not to be confused by other exising measures).

I hope this helps.

Thanks.
