Memory Issue with Avg Last 3 months Measure in Detailed Matrix Report

[Anonymous]

Hi PBI Expert, 

I've been trying on this calculation and it works when minumum amount of materials is filtered but will get into memory issue when i unfilter the material (can be up to 100++). However, user has request to view all materials in one go.

I have this matrix table per below.

the measure that i'm using is below:-

Avglast3mthRev =

var CurrentMonthOrder = MAX(Data[Period Number])

var company = ALLSELECTED(Data[Company])

var material = SELECTEDVALUE(Data[Material])

return

CALCULATE(divide([Rev],3),

filter(all(Data),

Data[Period Number]<=CurrentMonthOrder&&Data[Period Number]>=CurrentMonthOrder-2

&&Data[Company] in Company

&&Data[material] = material))

Can someone please help to take a look on how i can improve this? We have a huge database of the data thus keep causing memory issue whenever user request measure in detailed table.. 

Really Appreciate the help!!! 🙂

Thank you,

Celaeno

Hi, @Anonymous 

Try like this:

Avglast3mthRev =
VAR CurrentMonthOrder =
    MAX ( Data[Period Number] )
RETURN
    CALCULATE (
        DIVIDE ( [Rev], 3 ),
        FILTER (
            ALLSELECTED ( Data ),
            Data[Period Number] <= CurrentMonthOrder
                && Data[Period Number] >= CurrentMonthOrder - 2
        )
    )

If it doesn't solve your problem, Please feel free to ask me.

Best Regards

Try summarizing the table within Power Query using Group By. (I would suggest creating a reference query or a new one.  https://www.youtube.com/watch?v=kytYzjTXUHs Guy In a Cube channel has good guidance for this topic 🙂
