Anonymous , If you have separate table - Master/Reference for Tier, Then blank means that tables missing some entries used in fact/many side table 

for ltm using date table

Rolling 12 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date ],MAX('Date'[Date ]),-12,MONTH))

 

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :radacad sqlbi My Video Series Appreciate your Kudos.

    Thank for your quick response.

     

    I try the formula and it gave me the total sales qty cover that month in each column. ( as the tick below)

     

    However, i need it to show the same qty as "AllData.Qty" as my prior email attachment. In this case when i do the table ( as the black table attached) will show the same as CY.

     

    Sorry, i am new with Power BI and not sure what to fill up instead of "sum" in your formula. -  CALCULATE(sum(Sales[Sales Amount])

    Please advise.

     

    Thank you in advance.

      Anonymous , You are creating a column, and that will sum up all values. I am suggesting a measure. Try a measure and check.

       

      Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.
