*COMPLEX_SELECTIONS_DIALOG:开启输入多值对话框
TYPE-POOLS:icon."按钮上显示图标时需要调用该类库
DATA:l_count TYPE i."用于计算内表数值总数
DATA:lmail(50) TYPE c."定义mail地址输入变量长度及类型
*定义屏幕元素及文本元素
SELECTION-SCREEN:BEGIN OF BLOCK alv WITH FRAME TITLE text-002.
SELECTION-SCREEN:BEGIN OF LINE.
SELECTION-SCREEN:comment (14) text-001.
PARAMETERS:mailcopy LIKE lmail.
SELECTION-SCREEN:PUSHBUTTON 63(5) pubu USER-COMMAND mailbutt.
SELECTION-SCREEN:END OF LINE.
SELECTION-SCREEN:END OF BLOCK alv.
DATA:mailtype TYPE c VALUE ‘‘.
*定义一隐藏的SELECT-OPTIONS用于保存输入值
SELECT-OPTIONS:mailadd FOR lmail NO-DISPLAY.
AT SELECTION-SCREEN OUTPUT.
CLEAR l_count.
DESCRIBE TABLE mailadd LINES l_count.
*判断内表是否有值来设置按钮图标
IF l_count > 1.
WRITE icon_display_more AS ICON TO pubu.
ELSE.
WRITE icon_enter_more AS ICON TO pubu.
ENDIF.
AT SELECTION-SCREEN.
CLEAR l_count.
DESCRIBE TABLE mailadd LINES l_count.
*实现内表与文本元素间的值传递
IF NOT mailcopy IS INITIAL AND mailadd[] IS INITIAL.
mailadd-low = mailcopy.
APPEND mailadd.
ENDIF.
IF l_count = 1.
REFRESH mailadd.
CLEAR mailadd.

IF mailcopy IS INITIAL.
DELETE mailadd INDEX 1.
ELSE.
mailadd-low = mailcopy.
MODIFY mailadd INDEX 1 TRANSPORTING low.
