Hello, I'm using a Autogenerate Calendar and trying to get the current month and prior year month flags working.  My script is below.  I tried the suggestion marked correct from Getting Previous month date from current month date‌ but got an invalid expression when I substituted my date field.  Any help would be appreciated.

//Find max report year/month

Cal_Min_Max:

Load

max(DATE(MakeDate(LEFT(AS_OF_YYYYMM,4),'01',RIGHT(AS_OF_YYYYMM,2)),'DD/MM/YYYY')) as MaxCalDate,

min(DATE(MakeDate(LEFT(AS_OF_YYYYMM,4),'01',RIGHT(AS_OF_YYYYMM,2)),'DD/MM/YYYY')) as MinCalDate

FROM [lib://PRS_Auto_Inforce_QVD/AUTO_INFORCE.qvd]

(qvd);

//Store min and max inforce to a Variable

Let vMax_Inforce_Date = num(peek('MaxCalDate',0,'Cal_Min_Max'));

Let vMin_Inforce_Date = num(peek('MinCalDate',0,'Cal_Min_Max'));

drop table Cal_Min_Max;

Temp_Calendar:

LOAD 

               $(vMin_Inforce_Date) + Iterno()-1 As Num, 

               Date($(vMin_Inforce_Date) + IterNo() - 1) as TempDate 

               AutoGenerate 1 While $(vMin_Inforce_Date) + IterNo() -1 <= $(vMax_Inforce_Date); 

MasterCalendar: 

Load 

               TempDate AS OrderDate, 

               Month(TempDate) As Month, 

               YeartoDate(TempDate)*-1 as CurYTDFlag,

               Date( MonthEnd(addmonths(Max(Date#(TempDate ,'DD-MMM-YYYY')),-1)),'DD-MMM-YYYY')  as PRIOR_YEAR_MONTH,

               YeartoDate(TempDate,-1)*-1 as LastYTDFlag

Resident Temp_Calendar 

Order By TempDate ASC; 

Drop Table Temp_Calendar;

Few things

• The link you mentioned seem to be using the expression for front end not in script
  • therefore in script Max is not needed
  • also check the format that you have data in. your data seems to be in 'DD/MM/YYYY' according to top part of your script. so you will need to modify that
• in Prior_Year_Month - please explain what do you want there. i can try and help accordingly
• if its just LYTD and CYTD flag use below code (vToday is variable with current day)

  • InYearToDate(CalDate, '$(vToday)', 0) * -1 as CYTDFlag,

  •    InYearToDate(CalDate, '$(vToday)', -1) * -1 as LYTDFlag,

• In general i would recommend using script from below link for Master calendar. the link describes why

Hi Dilip, Thanks for responding.  I used the better calendar scripts from Rob W.  Works great!  Current month is not the month of today it is the month of the max INFORCE_DATE data in my fact set.  Here's my new calendar script that is working.  I just need to get the CM flag and a same month last year flag.

MasterCalendar: 

Load

TempDate AS INFORCE_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('INFORCE_DATE', recno()))-1 as mindate,

max(FieldValue('INFORCE_DATE', recno())) as maxdate

AUTOGENERATE FieldValueCount('INFORCE_DATE');

Use

InMonthToDate (TempDate, maxdate, 0)*-1 as CM_Flag

InMonthToDate (TempDate, maxdate, -12)*-1 as CM_PY_Flag

hope i understood correctly

Hi those added the flags correctly and the calendar works. Those flags will work for a static view but.  Now if I want to  have KPIs that show Current Month and Prior Year Month and be flexible based on the INFORCE_DATE selected. I have to do something else.  What I have tried is below.

I added the flags as suggested.  I also did a where exists because my data only has 1 inforce date so I don't need all the dates between each snapshot in my calendar.

CALENDAR: 

Load

TempDate AS INFORCE_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,

InMonthToDate (TempDate, maxdate, 0)*-1 as CM_Flag,

InMonthToDate (TempDate, maxdate, -12)*-1 as CM_PY_Flag,

WeekDay(TempDate) as WeekDay

where exists (INFORCE_DATE,TempDate)

;

//=== 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('INFORCE_DATE', recno()))-1 as mindate,

max(FieldValue('INFORCE_DATE', recno())) as maxdate

AUTOGENERATE FieldValueCount('INFORCE_DATE');

store CALENDAR into 'lib://PRS_Auto_Inforce_QVD/CALENDAR.qvd' (qvd);

drop table CALENDAR;

Using this it returns the correct value (left below with number erased):

Sum({<AS_OF_YYYYMM={$(=max(AS_OF_YYYYMM))}>}AUTO_ANNUAL_PREMIUM)

Using this it returns -.

Sum({<INFORCE_DATE={$(=(max(INFORCE_DATE)))}>}AUTO_ANNUAL_PREMIUM)

I was hoping to use the second expression and do -1 to get the prior date.

"Using this it returns -.

Sure that should work usually but if all date values are not present in the master calendar not sure how you can know which is the prior date

[carlcimino]

If the calendar only has month dates in it then why wouldn't Sum({<INFORCE_DATE={$(=(max(INFORCE_DATE)))}>}AUTO_ANNUAL_PREMIUM) work?  If I do Sum({<AS_OF_YYYYMM={$(=(max(AS_OF_YYYYMM)))}>}AUTO_ANNUAL_PREMIUM) it works. They are 1:1 in the data model.
