ALV GIRD를 만드는 방법 중 CLASS를 이용할 때...

첫번째 방식입니다. [Class 이용시]

CLASS 선언 부분

****************************************************************
* LOCAL CLASSES: Definition
****************************************************************
CLASS LCL_EVENT_RECEIVER DEFINITION.
  PUBLIC SECTION.
    METHODS : HANDLE_AFTER_USER_COMMAND
                     FOR EVENT AFTER_USER_COMMAND OF CL_GUI_ALV_GRID.
ENDCLASS. "(LCL_EVENT_RECEIVER DEFINITION)

************************************************************************
* LOCAL CLASSES: Implementation                                        *
************************************************************************
CLASS LCL_EVENT_RECEIVER IMPLEMENTATION.
  METHOD HANDLE_AFTER_USER_COMMAND.
     PERFORM AFTER_USER_COMMAND.
  ENDMETHOD.
ENDCLASS.                            "LCL_EVENT_RECEIVER IMPLEMENTATION
DATA: G_EVENT_RECE  TYPE REF TO LCL_EVENT_RECEIVER.

* EVENT 선언한 것을 객체로 만든다.

* EVENT 제어
  CREATE OBJECT G_EVENT_RECE.

* 이벤트제어 세팅

  SET HANDLER G_EVENT_RECE->HANDLE_AFTER_USER_COMMAND FOR G_ALV_GRID. " G_ALV_GRID는 ALV GIRD 객체 이름

* CLASS 선언 부분에서 METHOD 안에 PERFORM문 호출 Subrotin 입니다.

*&---------------------------------------------------------------------*
*&      Form  AFTER_USER_COMMAND
*&---------------------------------------------------------------------*
FORM AFTER_USER_COMMAND."USING P_UCOMM.
  DATA: L_TOTALINE TYPE SY-TABIX,
           L_FIDX TYPE LVC_T_FIDX.

 CALL METHOD G_ALV_GRID->GET_FILTERED_ENTRIES
      IMPORTING
           ET_FILTERED_ENTRIES =   L_FIDX.

  DESCRIBE TABLE GT_LIST LINES G_TOTALINE.
  DESCRIBE TABLE L_FIDX  LINES L_TOTALINE.
  G_TOTALINE = G_TOTALINE - L_TOTALINE.
  SET TITLEBAR  '0100' WITH G_TOTALINE.

ENDFORM.                    " AFTER_USER_COMMAND

두번째 방법입니다.[Function 이용시]

이부분은 제가 작성 해보고 다시 올릴께요~
