hi,
Try the following logic to find out the no.of working days in a month based on your calendar.
parameters : mny(6).    " input format should be  yyyymm
data : d1 like sy-datum,
       d2 like sy-datum,
       d3 like sy-datum,
       v_nds type i.
concatenate  mny '01' into d1.
CALL FUNCTION 'SLS_MISC_GET_LAST_DAY_OF_MONTH'
  EXPORTING
    DAY_IN            = d1
  IMPORTING
    LAST_DAY_OF_MONTH = d2
  EXCEPTIONS
    DAY_IN_NOT_VALID  = 1
    OTHERS            = 2.
IF SY-SUBRC <> 0.
  MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
          WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
do 30 times.
  CALL FUNCTION 'DATE_CONVERT_TO_FACTORYDATE'
    EXPORTING
      CORRECT_OPTION      = '+'
      DATE                = d1
      FACTORY_CALENDAR_ID = ' A'    " your factory calendar ID
    IMPORTING
      DATE                = d3.
  if d1 = d3.
    d1 = d1 + 1.
    v_nds = v_nds + 1.
  else.
    d1 = d3.
  endif.
  if d3 ge d2.
    exit.
  endif.
enddo.
write : 'No of working days ', v_nds.
hope it helps...
