master calender , only months and years required and financial month , it keeps creating duplicates

[vvvvvvizard]

I just want a calendar with Year Months , current calender below if i add a listbox shows eg Date 201301 201301 over and over again , i tried distinct  , i tried commenting out day , week , ect doesnt work , i think the problem is this code from below at the end

min(FieldValue('OrderDate', recno()))-1 as mindate,
max(FieldValue('OrderDate', recno())) as maxdate
AUTOGENERATE FieldValueCount('OrderDate');

Code begins here 

Sample_Date:
LOAD * inline [
OrderDate
201301  keep getting duplicates for Order date eg
201805
];

SET vFinYear_Month=10;

MasterCalendar:
LOAD * ,
'FQ' & Ceil(FiscalMonth/3) as FQuarter;
Load
TempDate AS OrderDate,
week(TempDate) As Week,
Year(TempDate) As Year,
Month(TempDate) As Month,
Date(Date#(Year(TempDate)*100+Month(TempDate),'YYYYMM'),'MMM-YY') as Month_Year,
Day(TempDate) As Day,
'Q' & ceil(month(TempDate) / 3) AS Quarter,
Week(weekstart(TempDate)) & '-' & WeekYear(TempDate) as WeekYear,
WeekDay(TempDate) as WeekDay ,
//////Fiscal Periods
YearName(TempDate, 0, $(vFinYear_Month)) AS FiscalYear,
Mod(Month(TempDate) - $(vFinYear_Month), 12)+1 AS FiscalMonth,
///////Flags normal calendar
if(InMonthToDate(TempDate,today(),0),1,0) as MTD,
if(InMonthToDate(TempDate,AddYears(today(),-1),0),1,0) as PYMTD,
if(InQuarterToDate(TempDate,today(),0),1,0) as QTD,
if(InQuarterToDate(TempDate,AddYears(today(),-1),0),1,0) as PYQTD,
if(InYearToDate(TempDate,today(),0),1,0) as YTD,
if(InYearToDate(TempDate,today(),-1),1,0) as PYTD,
///////Flags Financial calend
if(InYearToDate(TempDate,today(),0,$(vFinYear_Month)),1,0) as FYTD,
if(InYearToDate(TempDate,AddYears(today(),-1),0,$(vFinYear_Month)),1,0) as PFYTD,
if(InQuarterToDate(TempDate,today(),0,$(vFinYear_Month)),1,0) as FQTD,
if(InQuarterToDate(TempDate,AddYears(today(),-1),0,$(vFinYear_Month)),1,0) as PYfQTD,
;

//=== 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('OrderDate', recno()))-1 as mindate,
max(FieldValue('OrderDate', recno())) as maxdate
AUTOGENERATE FieldValueCount('OrderDate');

It would be great if it can be done in a subroutine
