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

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.

You also could refer to the attached pbix
