1，先把alv框架定出来
DATA: I_QMEL LIKE MAKT OCCURS 0.
DATA V_REPID TYPE REPID.
SELECT * FROM MAKT INTO TABLE I_QMEL.
V_REPID = SY-REPID.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
I_CALLBACK_PROGRAM = V_REPID 当前程序名
I_CALLBACK_PF_STATUS_SET = 'SET_PF_STATUS' 触发事件调用子程序
I_CALLBACK_USER_COMMAND = 'USER_COMMAND' 鼠标事件调用子程序
I_STRUCTURE_NAME = 'MAKT' 输入结构名
TABLES
T_OUTTAB = I_QMEL
EXCEPTIONS
PROGRAM_ERROR = 1
OTHERS = 2.
然后可以通过修改gui_status删除按扭或着增加按扭
2，接下来就是设定上面标红两个子程序(1). 用TCODE:se41,se80,se90(Programming
Library-->Programming SubObjects-->
Gui Status.)等都可以,拷贝一个标准的GUI status( 拷贝程序SAPLKKBL中的'STANDARD' GUI
status)到你的程序.
*&-------------------------------------------------------------------
*& Form set_pf_status，事件触发
*&-------------------------------------------------------------------
FORM set_pf_status USING rt_extab TYPE slis_t_extab.
SET PF-STATUS 'ALV_PF_STATUS'.
ENDFORM. "Set_pf_status
此FORM的作用是在标准的ALV工具栏上添加自定义的按钮
该名称必须和FUNCTION 参数I_CALLBACK_PF_STATUS_SET = 'SET_PF_STATUS'对应起来,即FORM的名称和变量名称要一样.
GUI
STATUS 'ALV_PF_STATUS'是自己定义的,因为自定义后会把标准的ALV工具栏覆盖,所以还要把标准工具栏复制过来.
方法如下:
（2）拷贝全功能工具栏,然后具体增加删减按键可通过se80里自定义工具栏名称进入修改
T-CODE ：SE90 Program
Library-- GUI Status
program
name:SAPLKKBL GUI
Status:STANDARD_FULLSCREEN 标准的ALV工具栏名称,F8运行,选择菜单栏GUI
Status---COPY,最后输入你的程序名以及你自定义的GUI
Status名,此例即为ALV_PF_STATUS,再添加按钮.
範例：
*&-------------------------------------------------------------------
*& Form ALV_USER_COMMAND
*&-------------------------------------------------------------------
* -->R_UCOMM text
* -->RS_SELFIELD text
*----------------------------------------------------------------------*
form ALV_USER_COMMAND using r_ucomm like sy-ucomm
rs_selfield type slis_selfield. "响应ALV点击自定义按钮之后的事件
case r_ucomm.
when 'EXIT2'. "在set pf-status '9100'.的屏幕状态里面自定义的按钮名称
LEAVE TO SCREEN 0.
WHEN '&DATA_SAVE'.
"修改屏幕字段物料描述MAKTX,此时的&DATA_SAVE是标准GUI的参数,I_CALLBACK_PF_STATUS_SET 不要进行设置
LOOP AT IT_MATNR.
READ TABLE IT_MATNR_OLD ASSIGNING <MATNR>
WITH KEY MATNR = IT_MATNR-MATNR.
CHECK IT_MATNR-MAKTX <> <matnr>-MAKTX.
UPDATE MAKT SET MAKTX = IT_MATNR-MAKTX WHERE MATNR = IT_MATNR-MATNR
AND SPRAS = 'M'.
ENDLOOP.
WHEN '&IC1'."表示双击
CHECK rs_selfield-tabindex > 0.
READ TABLE IT_MATNR INDEX rs_selfield-tabindex.
SET PARAMETER ID : 'MAT' FIELD IT_MATNR-MATNR.
CALL TRANSACTION 'MM03' AND SKIP FIRST SCREEN.
endcase.
rs_selfield-fieldname表示双击的字段名,有时候有用.
endform. "ALV_USER_COMMAND
