Gregorian Calendar - Week 53 not displayed

Question

Hello all,
My question is really quick : I'm displaying a DateNavigator in a Webdynpro Iview and the week 53 is missing.... how can I display it?
I changed the Location values :
- the default location is en_US
- the location in parameter is FRENCH
I tried to modify the location but nothing append. I'd like to switch between US configuration and FRANCE configuration to see the differences but for now I only have the US configuration (Sunday as the 1st day of week)
I'll give you a part of my code, maybe you will see what's wrong in it :
public static void wdDoModifyView(IPrivateVCalendar wdThis, IPrivateVCalendar.IContextNode wdContext, com.sap.tc.webdynpro.progmodel.api.IWDView view, boolean firstTime)
    //@@begin wdDoModifyView
          if (firstTime) {
               IWDDateNavigator myCalendar = (IWDDateNavigator) view.getElement("DateNavigator");
               myCalendar.mappingOfOnWeekSelect().addSourceMapping("year", "year");
               myCalendar.mappingOfOnWeekSelect().addSourceMapping("week", "week");
               myCalendar.mappingOfOnDaySelect().addSourceMapping("day", "day");
               GregorianCalendar myDate = new GregorianCalendar(Locale.GERMANY);
               myDate.setTimeInMillis(System.currentTimeMillis());
               wdThis.updateDatesCalendar(myDate.get(Calendar.YEAR), myDate.get(Calendar.WEEK_OF_YEAR));
    //@@end
Thank you for your help.
Regards

Hi Rajesh,
The occurence of a 53rd week is internationally standardized. The check in BW follows these international conventions which count the week depending on the majority of days:
- if the week has 4 days of the old year it counts as CW53;
- if it has 4 days of the new year it is CW1.
That is to say, the number of ISO weeks belonging to a year number is equal to the number of Thursdays in the correspondingly-numbered calendar year, and is equal to the week number of December 31st; and a year has 53 weeks if, and only if, the following day is in its Week 53.
The 53-week years in the range 2000-2027 are: 2004, 2009, 2015, 2020, 2026.
That pattern repeats every 28 years before 2100.
For 0CALWEEK, it will calculate the week based on the calendar you specified in tcode RSRHIERARCHYVIRT. Please note that RSRHIERARCHYVIRT is a BW global setting, i.e. that means the system will use this calendar for all data targets.
If you have some special business impact to include a 201153, please check the following:
1. write a routine in the transfer rules for 0CALWEEK that modifies into the week 201201.
2. manually correct the data in the PSA and load from PSA into the target cube.
Rgds,
