Hi,

Refer this expression -

sum({<Date = {'>$(=(date(AddMonths( date#(max(Date),'DD/MM/YYYY'),-3),'DD/MM/YYYY')))'}>}Amount)

Temp_Data:
Load * Inline
[
  Date
  12/01/2015
  13/02/2015
  15/02/2015
  18/04/2015
  21/06/2015
  01/07/2015
  08/07/2015
  30/09/2015
  31/10/2015
  21/11/2015
  22/12/2015
];


Left Join (Temp_Data)
Load Date, RowNo() as ID Resident Temp_Data Order By Date Desc;


NoConcatenate
Final:
Load Date Resident Temp_Data
Where ID <= 3
Order By ID;


Drop Table Temp_Data;

at Front End

=SUM({<ID = {">=$(=Max(ID)-2)<=$(=Max(ID))"}>}ID)

or

=SUM({<ID = {">=$(=Max(ID)-2)<=$(=Max(ID))"}>}YourFactDataFieldName)
