LTM in Power BI

[Anonymous]

Dear expert

I have a question regarding LTM formula and hope anyone could help.

I would like to create a "LTM sales" and "LTM Qty" columns which can show "AllData.Sales" and "AllData.Qty" during LTM and show "blank" if is's unrelated. And i will be able to create a table in Power BI (as the second attached table) and looks like "CY" one.  

Thank you in advance.

@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.
