1st :
In this table; create a date field :
YourTable;
Load * ,
date(Date#(Subfield(DATE,' ',1),'DD/MM/YYYY')) as DateField
from source;
Then create a master Calendar as follow:
QuartersMap:
MAPPING LOAD
rowno() as Month,
'Q' & Ceil (rowno()/3) as Quarter
AUTOGENERATE (12);
Temp:
Load
min(DateField) as minDate,
max(DateField) as maxDate
Resident YourTable;
Let varMinDate = Num(Peek('minDate', 0, 'Temp'));
Let varMaxDate = Num(Peek('maxDate', 0, 'Temp'));
DROP Table Temp;
TempCalendar:
LOAD
$(varMinDate) + Iterno()-1 As Num,
Date($(varMinDate) + IterNo() - 1) as TempDate
AutoGenerate 1 While $(varMinDate) + IterNo() -1 <= $(varMaxDate);
MasterCalendar:
Load
TempDate AS DateField,
week(TempDate) As Week,
Year(TempDate) As Year,
Month(TempDate) As Month,
Day(TempDate) As Day,
YeartoDate(TempDate)*-1 as CurYTDFlag,
YeartoDate(TempDate,-1)*-1 as LastYTDFlag,
inyear(TempDate, Monthstart($(varMaxDate)),-1) as RC12,
date(monthstart(TempDate), 'MMM-YYYY') as MonthYear,
ApplyMap('QuartersMap', month(TempDate), Null()) as Quarter,
Week(weekstart(TempDate)) & '-' & WeekYear(TempDate) as WeekYear,
WeekDay(TempDate) as WeekDay
Resident TempCalendar
Order By TempDate ASC;
Drop Table TempCalendar;
Then please refer to this link to create ur YTD MTD WTD QTD expressions (I tried to explain how to do it step by step)
