Need help SUM or AVERAGE last 7 Previous Records (Not Using Date)

[thollitez]

Hi Guys,

I've been checking the forum and google regarding SUM or AVERAGE last specific number of records.

All solutions i've found is using DATE, but DATE is irrelevant on what i am trying to attain.

What i am really trying to attain is get the AVERAGE of last 7 records regardless of the dates.

Please see example below.

 

Thanks in advance.

Hi @thollitez,

For your scenario, you should create an index column in Query Editor and create the measure below.

1. Create Index column

2. Create the measure under Modeling tab.

Moving Average last 7 Records =
VAR SevenrecordsTotal =
    CALCULATE (
        SUM ( 'table'[UNITS SOLD] ),
        FILTER (
            ALL ( 'table'[Index] ),
            'table'[Index] <= MAX ( 'table'[Index] )
                && 'table'[Index]
                    >= MAX ( 'table'[Index] ) - 6
        ),
        ALL ( 'table' )
    )
VAR Records =
    CALCULATE (
        DISTINCTCOUNT ( 'table'[Index] ),
        FILTER (
            ALL ( 'table'[Index] ),
            'table'[Index] <= MAX ( 'table'[Index] )
                && 'table'[Index]
                    >= MAX ( 'table'[Index] ) - 6
                && 'table'[Index] <> BLANK ()
        ),
        ALL ( 'table' )
    )
RETURN
    IF ( SUM ( 'table'[Index] ) >= 7, DIVIDE ( SevenrecordsTotal, Records ), BLANK () )

Then you could get the output below.
