Hi  @naveen567 ,

 

you need to create a Master Calendar in the Load Script and associate it to your Date field as follows:

MasterCalendar: 
Load 
 TempDate AS Date, 
 week(TempDate) As Week, 
 Year(TempDate) As Year, 
 Month(TempDate) As Month, 
 Day(TempDate) As Day, 
 'Q' & ceil(month(TempDate) / 3) AS Quarter, 
 Week(weekstart(TempDate)) & '-' & WeekYear(TempDate) as WeekYear, 
 WeekDay(TempDate) as WeekDay 
;

//=== Generate a temp table of dates === 
LOAD 
 date(mindate + IterNo()) AS TempDate
 ,maxdate // Used in InYearToDate() above, but not kept 
WHILE mindate + IterNo() <= maxdate;

//=== Get min/max dates from Field ===/
LOAD
 min(FieldValue('Date', recno()))-1 as mindate,
 max(FieldValue('Date', recno())) as maxdate
AUTOGENERATE FieldValueCount('Date');

I agree, building a  Master calender is the best  idea.


Here is a good article to understand zu Master Calender.
