Number of weekdays

Question

I need to find the number of week days(mon-fri) in a given month. I have used the FM DATE_CONVERT_TO_FACTORYDATE to get the difference between the first and the last day of the month. However it is not giving me the correct output. could someone please let me know how I can get the desired output?

Hello,
In your system, there would be one or more calendars defined, get the 2 byte calendar id to be used to get check the holiday from the functional people (or check txn SCAL, or tables THOC*).
Now, you have some function modules you can use to check the work-days (I do not think you have one which will give you the no of working days for a period, so you may have to run it for each date to count the no of days), the code may look like
*say your period is from w_fromdate to w_todate, and
calendar is in w_calid
data : w_date like sy-datum.
data : no_of_workdays type i.
w_date = w_fromdate.
do.
CALL FUNCTION 'DATE_CHECK_WORKINGDAY'
         EXPORTING
              DATE                       = w_date
              FACTORY_CALENDAR_ID        = w_calid
              MESSAGE_TYPE               = 'W'
         EXCEPTIONS
              DATE_AFTER_RANGE           = 1
              DATE_BEFORE_RANGE          = 2
              DATE_INVALID               = 3
              DATE_NO_WORKINGDAY         = 4
              FACTORY_CALENDAR_NOT_FOUND = 5
              MESSAGE_TYPE_INVALID       = 6
              OTHERS                     = 7.
    IF SY-SUBRC eq 0.
       no_of_workday = no_of_workday + 1.
    endif.
   w_date = w_date + 1.
   if w_date gt w_todate.
      exit.
   endif.
enddo.
*no_of_workdays shall get you the count of work days
