Add calendar weeks with number - turn of the year

[reporting_neu]

Hi,
the report always shows data from the current week and then from the next week and the one after that, up to 12 weeks in the future.

(KW = calendar week)

In the report, the employee can select the year and the calendar week in selection box.

So I use for the next Week: 

GetFieldSelections([MASTER_CAL.Week])+1

For the week after:

GetFieldSelections([MASTER_CAL.Week])+2

then +3, +4, ...+12

But now the year ends in calendar week 52 and it shows week 53 instead of 1.

How can I adjust the formula so he knows a new year is about to begin?

In the calculations I use:

Sum({1<[WPL.Week] = {"$(=[MASTER_CAL.Week]+12)"}, [WPL.Year] = {"$(=Year(Today()))"}>}[WPL.Capacity])

Can you help me please? 🙂

Unfortunately I have to ask again:

Does anyone know how I can add calendar weeks when a new year is coming up? 😔

Like:
Current Calendar Week is 49.

[CalendarWeek]+1 = 50
[CalendarWeek]+2 = 51
[CalendarWeek]+3 = 52
[CalendarWeek]+4 = 1 (new Year)

I can't handle the turn of the year.
