## How can I create a calculated column that calculates the running total of the last 13 periods?

This table contains several rich identifiers that should be took in consideration when calculating the running total.

Should I create a calculated column or a measure?

The thing is that when creating the measure, and adding it to a matrix, slicers dont work if I want to only see information for a specific country.  If I apply a filter by country the measure shows the values for all rows with the country selected, and the other countries show the sum of the entire table, and still appear in the table instead of dissapearing.

I have a week column identifier, and I added an index column to enumerate each column them.

This is the code I was using for the measure, so the current week and the previous weeks can have their own running total taking in consideration the previous 13 weeks.

Sum of 13 Previous Weeks Total Units =

CALCULATE([Sum of Total Units],

FILTER(ALL('Table1'), 'Table1'[Index]=SELECTEDVALUE('Table1'[Index]) ||

'Table1'[Index]=SELECTEDVALUE('Table1'[Index])+1 ||

'Table1'[Index]=SELECTEDVALUE('Table1'[Index])+2 ||

'Table1'[Index]=SELECTEDVALUE('Table1'[Index])+3 ||

'Table1'[Index]=SELECTEDVALUE('Table1'[Index])+4 ||

'Table1'[Index]=SELECTEDVALUE('Table1'[Index])+5 ||

'Table1'[Index]=SELECTEDVALUE('Table1'[Index])+6 ||

'Table1'[Index]=SELECTEDVALUE('Table1'[Index])+7 ||

'Table1'[Index]=SELECTEDVALUE('Table1'[Index])+8 ||

'Table1'[Index]=SELECTEDVALUE('Table1'[Index])+9 ||

'Table1'[Index]=SELECTEDVALUE('Table1'[Index])+10 ||

'Table1'[Index]=SELECTEDVALUE('Table1'[Index])+11 ||

'Table1'[Index]=SELECTEDVALUE('Table1'[Index])+12 &&

'Table1'[Country]= SELECTEDVALUE('Table1'[Country]) && ..... (repeats for each rich identifer)

))

Thank you in advance for the guidance

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

with help from week Index or Rank you can can rolling measure easily

example

rank or index(if only week wise data. Use a seperate week or date Table

Week Rank = RANKX(all('Date'),'Date'[Year Week],,ASC,Dense) //YYYYWW format
measures

Last 13 weeks = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]>=max('Date'[Week Rank])-13 && 'Date'[Week Rank]<=max('Date'[Week Rank])))
