    Hi,

     

    Did you have a calendar table with relationship with your fact table?

     

    You can use the following dax to calculted rolling average inventory for last 12 months:

     

    measure =
VAR _DATE =
    SELECTEDVALUE ( 'Date'[Date] )
RETURN
    CALCULATE (
        SUM ( 'Table'[Inventory] ),
        DATESBETWEEN ( 'Date'[Date], DATEADD ( _DATE, -12, MONTH ), _DATE )
    ) / 12

     

    It will be the same for Net Sales. Or you can use quick measure in power bi to calculate rolling average. Please refer to https://www.mssqltips.com/sqlservertip/5635/creating-a-rolling-average-graph-with-power-bi/.

     

    It will be nice if you can show us some sample data by onedrive for business.

     

    Best Regards,

    But my client is asking average inventory calculation like below

     

    From the selected date by user say 04.06.2020,

    go backward and check inventory value on 04.06.20, 04.05.20…………….. 04.07.19 (12 months)

    Add all twelve months inventory and divide it by 12 so that you will get average inventory.
