    Hi cst_bi ,

     

    According to your statement, I think your issue should be caused by that you remove [item] from your table visual. So [safety] measure will be summarized based on data in your table visual.

    I could reproduce your issue in my sample.

    Data model:

    avg = AVERAGE('purchase table'[qty])/3
    standard_deviation = STDEVX.S('issue table','issue table'[qty])
    safety = [avg] * [standard_deviation]

    Here I suggest you to create a new measure for this visual.

    safety for group = 
AVERAGEX(VALUES('item_master table'[item]),[safety])

    Result is as below.

    Best Regards,
    Rico Zhou

    Hi Anonymous ,

    Thank you,

    But why join all code not work :

    safety for group = 
    var safety = [avg] * [standard_deviation]
    return AVERAGEX(VALUES('item_master'[item]),safety)

    It's only work when :
    safety = [avg] * [standard_deviation]
    safety for group = AVERAGEX(VALUES('item_master'[item]),[safety])
     

    If there's any simple references how the logic/architecture of dax engine work, please let me know

    Sincerely,
