關於ICON的顯示和輸出

1、定義欄位
data: status_icon type icons-text.

2、建立螢幕，並在螢幕定義建立一個"Status Icon"控制項 ,命名為:status_icon

3、利用ICON_CREATE函數在輸出是設定ICON。
  call function 'ICON_CREATE'
       exporting
            name                  = 'ICON_GREEN_LIGHT'
            text                       = '表徵圖後面顯示的文本'
            info                      = '提示'
            add_stdinf            = 'X'
       importing
            result                = status_icon
       exceptions
            icon_not_found        = 1
            outputfield_too_short = 2
            others                = 3.

4、sap的表徵圖可以使用ICON_SHOW函數顯示列出
call function 'ICON_SHOW' exporting onlydisplay = 'X'
                          exceptions no_object_found = 1
                                     no_icon_selected = 2.

5、關於表徵圖的範例可參見sap的示範代碼：DEMO_DYNPRO_STATUS_ICONS
