Rolling 12 months filter

[Prabha45]

Hi, I want to filter my data on the last 12 months period. For instance if I select year as 2022 and month as Jan, I want the data to be filtered on the last 12 months such as from Jan 2021 till Jan 2022.
Is it possible to have a 12 months flag on complete page. I have a table visual with columns from data source, no dax is involved in this table and a couple of cards having count of a column.
I've been trying a lot of solutions but nothing worked out. Would appreciate if anyone can help in this.

@Prabha45 you can create a calc column in your main date table. Below calc will calc months from today and you can apply filter accordingly in your data to show months greater than -12.

MonthsFromToday = DATEDIFF(TODAY(), 'Calendar'[Date],MONTH)

@Prabha45 , if you want to show rolled up data of 12 month you can have measure like this with help from date table

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

But if you want to show 12 month trend on the axis, you need a slicer on an independent date table

//Date1 is independent Date table, Date is joined with Table
new measure =
var _max = maxx(allselected(Date1),Date1[Date])
var _min = eomonth(_max, -12) +1
return
calculate( sum(Table[Value]), filter('Date', 'Date'[Date] >=_min && 'Date'[Date] <=_max))

Thanks for you reply. But, there is no need of calculation of columns. Table visual is having only the columns (Name, description, date, department) coming from data source. No measures are used in this table.

@Prabha45 , Not clear on "no need of calculation of columns" and "No measure"

I suggested measures. Would need more information, what is needed

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