How to get the number of months on selection screen?

[former_member720770]

Here's coding of F4 to select only year and month.

Now to calculate, I want the variable of number of months on select options, how to do it?

Thanks a lot!

FORM FRM_GET_F4 USING VALUE (PVF_DYNPRO FIELD). 
Data LDF_MONAT TYPE ISELLIST-MONTH. 
FIELD-SYMBOLS <FS_FIELD> TYPE ANY. 
LDF_MONAT = SY-DATUM + 0(6).

CALL FUNCTION 'POPUP_TO_SELECT_MONTH'
EXPORTING  
  ACTUAL_MONTH = LDF_MONAT
IMPORTING 
  SELECTED_MONTH = LDF_MONAT
EXCEPTIONS
~

IF SY-SUBRC = 0. 
  CHECK LDF_MONAT <> '000000'.
  ASSIGN (PVF_DYNPROFIELD) TO <FS_FIELD>. 
  IF <FS_FIELD> IS ASSIGNED. 
    <FS_FIELD> = LDF_MONAT.
    UNASSIGNED <FS_FIELD>. 
  ENDIF. 
 ENDIF.

Hello,

Please check below code.

TABLES : s001.

DATA : _date_range     TYPE RANGE OF mseg-budat_mkpf,
       _start_day      TYPE mseg-budat_mkpf,
       _last_day       TYPE mseg-budat_mkpf,
       _actual_month   TYPE isellist-month,
       _selected_month TYPE isellist-month.

SELECT-OPTIONS : s_monyr FOR s001-spmon NO INTERVALS OBLIGATORY.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR s_monyr-low.
  IF s_monyr[] IS INITIAL.
    s_monyr-sign = 'I'.
    s_monyr-option = 'EQ'.
    s_monyr-low = sy-datum+0(6).
    APPEND s_monyr.
  ENDIF.
  TRY.
      _actual_month = s_monyr[ 1 ]-low+0(6).
    CATCH cx_sy_itab_line_not_found.
  ENDTRY.
  CALL FUNCTION 'POPUP_TO_SELECT_MONTH'
    EXPORTING
      actual_month               = _actual_month
    IMPORTING
      selected_month             = _selected_month
    EXCEPTIONS
      factory_calendar_not_found = 1
      holiday_calendar_not_found = 2
      month_not_found            = 3
      OTHERS                     = 4.
  IF sy-subrc IS INITIAL.
    ASSIGN s_monyr[ 1 ] TO FIELD-SYMBOL(<fs_monyr>).
    IF <fs_monyr> IS ASSIGNED.
      <fs_monyr>-low = s_monyr-low = _selected_month.
    ENDIF.
  ENDIF.
