ABAP OOALV模板

自用模板，可能存在问题

一、主程序

*&---------------------------------------------------------------------*
*& Report ZVIA_OO_ALV
*&---------------------------------------------------------------------*
REPORT ZVIA_OO_ALV.INCLUDE ZVIA_OO_ALV_TOP1."OO ALV定义相关 （可能需要修改）
INCLUDE ZVIA_OO_ALV_TOP2."程序数据定义相关 （需要修改）
INCLUDE ZVIA_OO_ALV_S01."选择屏幕，获取用户输入 （需要修改）
INCLUDE ZVIA_OO_ALV_F01."取数逻辑等子例程 （需要修改）
INCLUDE ZVIA_OO_ALV_F02."OO ALV 相关 （需要修改）START-OF-SELECTION.PERFORM FRM_GET_DATA.END-OF-SELECTION.CALL SCREEN 2000.

二、OO ALV定义相关

*&---------------------------------------------------------------------*
*& 包含               ZVIA_OO_ALV_TOP1
*&---------------------------------------------------------------------*
DATA:gv_ucomm TYPE sy-ucomm,ok_code  TYPE sy-ucomm.DATA:gv_col_pos             LIKE sy-cucol,g_wa_allfields         TYPE lvc_s_fcat,g_grid_alv             TYPE REF TO cl_gui_alv_grid, "列表g_container_alv        TYPE scrfname VALUE 'GC_2000', "容器 （可能需要修改）g_custom_container_alv TYPE REF TO cl_gui_custom_container,gw_layout_alv          TYPE lvc_s_layo,gt_fieldcat_alv        TYPE lvc_t_fcat,gw_fieldcat_alv        TYPE lvc_s_fcat,gw_exclude_alv         TYPE ui_func,gt_exclude_alv         TYPE TABLE OF ui_func.*OO ALV Display*
DATA:go_alv TYPE REF TO cl_gui_alv_grid."声明ALV对象

 需要创建屏幕2000

三、程序数据相关

*&---------------------------------------------------------------------*
*& 包含               ZVIA_OO_ALV_TOP2
*&---------------------------------------------------------------------**根据报表数据结构来定义内表和结构体*
DATA:git_stu TYPE STANDARD TABLE OF zvia_stu,"内表gw_stu  TYPE zvia_stu."结构体TABLES:zvia_stu."使用到的表

四、选择屏幕

确认要使用到的用户选择字段

*&---------------------------------------------------------------------*
*& 包含               ZVIA_OO_ALV_S01
*&---------------------------------------------------------------------*
SELECT-OPTIONS:s_id FOR zvia_stu-stuid.

五、 取数逻辑等子例程

写自己的取数逻辑，这里写的比较简单

*&---------------------------------------------------------------------*
*& 包含               ZVIA_OO_ALV_F01
*&---------------------------------------------------------------------*
*&---------------------------------------------------------------------*
*& Form FRM_GET_DATA
*&---------------------------------------------------------------------*
*& 取数逻辑
*&---------------------------------------------------------------------*
*& -->  p1        text
*& <--  p2        text
*&---------------------------------------------------------------------*
FORM frm_get_data .SELECT *from  ZVIA_STUINTO TABLE git_stuWHERE stuid in s_id.
ENDFORM.
