load Period, Addmonths(Period,11,1) as RollingPeriod, year(Addmonths(Period,11,1)) as RollingYear Resident b; 

have have a table being imported via SQL server and its called Orders and a column called OrderDate.. i would like to use the code above to help me create a selection filter that shows a number of months and if you click any of the months it will roll back 12 months e.g "April" it would then be April 30th backwards, all tables and kpi and scatters graphs in the sheets will reflect this.  but i cannot get it to work.

i have created a time and date calendar

Calendar: DECLARE FIELD DEFINITION TAGGED '$date' Parameters first_month_of_year = 1 Fields

     Year($1) As Year Tagged '$year',

     Month($1) as Month Tagged '$month',

     Date($1) as Date Tagged ('$date', '$day'),

     Week($1) as Week Tagged '$week',

     Weekday($1) as Weekday Tagged '$weekday',

     DayNumberOfYear($1, first_month_of_year) as DayNumberOfYear Tagged ('$numeric');

DERIVE FIELDS FROM FIELDS [OrderDate] USING Calendar;

Please help

Kind Regards
