    Hi volt26 

     

    Sure, you can try this:

    MEASURE =
VAR _vtable =
    SUMMARIZE ( ALLSELECTED ( 'Table' ), 'Table'[ID], 'Table'[Num], "_AVG", [AVG] )
RETURN
    AVERAGEX ( _vtable, [_AVG] )

    The result is as follow:

Hi volt26 

 

Please try this:

AVG =
VAR _currentID =
    SELECTEDVALUE ( 'Table'[ID] )
VAR _currentNum =
    MAX ( 'Table'[Num] )
VAR _vtable =
    ADDCOLUMNS (
        ALLSELECTED ( 'Table' ),
        "_product", 'Table'[Values] * 'Table'[Vendu]
    )
VAR _vtable2 =
    SUMMARIZE (
        _vtable,
        'Table'[ID],
        'Table'[Num],
        "_Sum",
            SUMX (
                FILTER ( _vtable, [ID] = EARLIER ( [ID] ) && [Num] = EARLIER ( [Num] ) ),
                [_product]
            )
    )
RETURN
    SUMX (
        FILTER (
            _vtable2,
            [ID] = SELECTEDVALUE ( 'Table'[ID] )
                && [Num] = MAX ( 'Table'[Num] )
        ),
        [_Sum]
    )
        / SUMX (
            CALCULATETABLE (
                VALUES ( 'Table'[Vendu] ),
                FILTER (
                    ALLSELECTED ( 'Table' ),
                    'Table'[ID] = _currentID
                        && 'Table'[Num] = _currentNum
                )
            ),
            [Vendu]
        )

The result is 8.67:

If you want 130, please change the return into:

SUMX (
    FILTER (
        _vtable2,
        [ID] = SELECTEDVALUE ( 'Table'[ID] )
            && [Num] = MAX ( 'Table'[Num] )
    ),
    [_Sum]
)
    / CALCULATE (
        COUNT ( 'Table'[Num] ),
        FILTER (
            ALLSELECTED ( 'Table' ),
            'Table'[ID] = _currentID
                && 'Table'[Num] = _currentNum
        )
    )

The result is as follow:

Wow! What you did is fantastic!
I'll push my luck and ask an extra question but if this should be in another thread simply tell me I will do so. I'm aware that you probably want me to click the accept as solution button by now! 🙂

 

So...

Now that I have the AVG for each selected cycle, is it possible to have a column that will show the average of the averages? Like this :

 

(sum of all selected Num columns)/(amount of Num columns selected) = Average of averages
(4+7+1+8.67+9)/5=5.934
