HI ,

since i using methods i can do perform,

can i do it it better way instead of using the same logic for 3 time ,

Thanks

Chris

lt_type_format = me->get_domain_value( ms_defultes ).

IF is_dev-date_format IS INITIAL.
    READ TABLE lt_type_format ASSIGNING <ls_type_format>
    WITH KEY domain_name = clconstants=>gc_date_type.
    is_de-date_format =   <ls_type_format>-format_value."Get date format
  ENDIF.

  IF is_de-time_format IS INITIAL.
    READ TABLE lt_type_format ASSIGNING <ls_type_format>
    WITH KEY domain_name = clconstants=>gc_time_type.
    is_de-time_format =   <ls_type_format>-format_value."Get time format
  ENDIF.

  IF is_de-num_format IS INITIAL.
    READ TABLE lt_type_format ASSIGNING <ls_type_format>
    WITH KEY domain_name = clconstants=>gc_dec_type.
    is_de-num_format  =   <ls_type_format>-format_value."Get dec notation
  ENDIF.

Yes you can.

Create your lt_type_format as the attribute of your class.

Create a method say GET_FORMAT

Signature:

Importing IV_TYPE TYPE CHAR30 (pass clconstants=>gc_date_type or clconstants=>gc_time_type)

Returning RV_FORMAT TYPE CHAR30 ( Recieve the value back)

Use the Read statement to read the table LT_TYPE_FORMAT and send back the values in RF_FORMAT

Like:


CLASS lcl_format DEFINITION.
  PUBLIC SECTION.
    METHODS:
      constructor,
      get_format
        IMPORTING
          iv_type TYPE char30
        RETURNING value(rv_format) TYPE char30.
  PRIVATE SECTION.
    TYPES: BEGIN OF ty_tab,
             format_type TYPE char30,
             format      TYPE char30,
           END   OF ty_tab.
    DATA: i_tab TYPE STANDARD TABLE OF ty_tab.
ENDCLASS.                    "lcl_format DEFINITION

START-OF-SELECTION.
  DATA: o_format TYPE REF TO lcl_format,
        lv_date_format TYPE char30,
        lv_time_format  TYPE char30.
  CREATE OBJECT o_format.
  lv_date_format = o_format->get_format( 'D' ).
  WRITE: / lv_date_format.
  lv_time_format = o_format->get_format( 'T' ).
  WRITE: / lv_time_format.

CLASS lcl_format IMPLEMENTATION.

  METHOD constructor.
    FIELD-SYMBOLS: <lfs_tab> LIKE LINE OF me->i_tab.
    APPEND INITIAL LINE TO me->i_tab ASSIGNING <lfs_tab>.
    <lfs_tab>-format_type = 'D'.
    <lfs_tab>-format = 'MM/DD/YYYY'.
    APPEND INITIAL LINE TO me->i_tab ASSIGNING <lfs_tab>.
    <lfs_tab>-format_type = 'T'.
    <lfs_tab>-format = 'HHMMSS'.
  ENDMETHOD.                    "constructor

  METHOD get_format.
    FIELD-SYMBOLS: <lfs_tab> LIKE LINE OF me->i_tab.
    DATA: lv_key TYPE string.
    READ TABLE me->i_tab ASSIGNING <lfs_tab>
      WITH KEY format_type = iv_type.
    IF sy-subrc = 0.
      rv_format = <lfs_tab>-format.
    ENDIF.
  ENDMETHOD.                    "get_format

ENDCLASS  .                    "lcl_format IMPLEMENTATION

what is the purpose of APPEND INITIAL LINE TO ?

When you use the field-symbols instead of the work area, you need to use the APPEND INITIAL LINE.. ASSIGNING <FS> to assign that new line to your Field-Symbol.

Code with Work area


DATA: WA_TAB LIKE LINE OF ITAB.
WA_TAB-FIELD1 = 'TEST'.
APPEND WA_TAB TO ITAB.

And code with Field-symbols:


FIELD-SYMBOLS: <FS_TAB> LIKE LINE OF ITAB.
APPEND INITIAL LINE TO ITAB ASSIGNING <FS_TAB>.
<FS_TAB>-FIELD1 = 'TEST'.

Achieve the same end result, it appends a line to Internal table.
