CY & PY AsofTAble in mastercalendar

[philgood34]

Hi

I try to learn about CURRENT & PREVIOUS YEARS with a AsofTable in script

i have 1 tab

From another thread i imported and adapted this script

[DATA]:

LOAD Date(MakeDate([YEAR], [MONTH]), 'MM_YYYY') as MonthYear,

[YEAR],

[MONTH],

[SECTORS],

[SALES]

FROM [lib://RANK_FLAG/DATAS.xlsx]

(ooxml, embedded labels, table is DATA);

AsOfTable:

LOAD MonthYear as AsOfMonthYear,

MonthYear,

     'CY' as Flag

Resident [DATA];

Concatenate (AsOfTable)

LOAD MonthYear as AsOfMonthYear,

Date(AddYears(MonthYear, -1), 'MM_YYYY') as MonthYear,

     'PY' as Flag

Resident [DATA];

Set vFM = 1;

QuartersMap: 

MAPPING LOAD  

rowno() as Month, 

'Q' & Ceil (rowno()/3) as Quarter 

AUTOGENERATE (12); 

Temp: 

Load 

               min(AsOfMonthYear) as minDate, 

               max(AsOfMonthYear) as maxDate 

Resident AsOfTable; 

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 Dual(fYear-1 &'/'& fYear, fYear) as FYear,          // Dual fiscal year

         Dual(Month, fMonth)                as FMonth,           // Dual fiscal month

          *;

LOAD Year + If(Month >= $(vFM), 1, 0) as fYear,         // Numeric fiscal year

     Mod(Month-$(vFM), 12)+1        as fMonth,          // Numeric fiscal month

     *;

Load 

               TempDate AS AsOfMonthYear, 

               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; 

The result is :

NO PREVIOUS VALUES 😞

and this

Previous = current

Can you help me to understand with a right script please ?

thank's by advance
