Date determination

[alex_georgek]

Hi Experts,

I have a requirement to calcuate the weeks start date  for a particular location say location 1.In this location it is configured that the 1st day for a month starts with Thursday.So based on this i need to calculate the week start date.Say for example

In selection screen i have 3 fields: month week and week start date.My requirement is to calcualte the week start date for a particular location when the user enter month and week.

If current system date is 2012/01/10 (Tuesday) (month 1, week 2) and user inputs month 1, week 3.

If working in location1 (based on configuration for location 1 : start day is Thursday and end date is  Wednesday), the first day of working week (week 3) should be Thursday (2012/01/12) .

How to do this technically....

Thanks in advance,

Alex

Try this (if I understood everything correctly):

form get_first
   using
* Weekday with which week starts: 0 = Sunday, 1 = Monday,... :
     iv_weekday_week_start type i
* Desired week number 1 = first, 2 = second, ... :
     iv_week_number_in_month type i
* Reference Month
     iv_ref_month            type char02
     iv_ref_year             type char04
   changing
     ev_week_start           type d.

   data: lv_first_of_month type d.

   concatenate iv_ref_year iv_ref_month '01' into lv_first_of_month.

    ev_week_start =
      ( iv_weekday_week_start + 1 - lv_first_of_month ) mod 7
      + 7 * ( iv_week_number_in_month - 1 )
      + lv_first_of_month.

endform.

Hi Alex,

I am confused. You say that in your scenario, the first day of the month for a particular location is Thursday. So, shouldn't that mean that Thursday would be the starting day for all working weeks in that month?
