ALV標準功能彙總，分類彙總，排序，過濾這些功能除了可以直接使用它的標準功能按鈕之外，你也可以在程序裏設定，讓ALV列表第一次顯示出來就已經使用了這些功能。
用REUSE_ALV_GRID_DISPLAY實現的ALV不能在程序設定輸出字段的平均值，最小值，最大值等標準功能。用OO方式實現ALV輸出的就可以，請參考

一、排序
排序用到類型slis_t_sortinfo_alv，按條件把過濾的字段和規則設置好，添加到一個參考slis_t_sortinfo_alv類型的內表，在調用Function的時候指導內表賦給it_sort參數
二、過濾
過濾用到類型slis_t_filter_alv，按條件把排序的字段和規則設置好，添加到一個參考slis_t_filter_alv類型的內表，在調用Function的時候把內表的值賦給it_fitler參數
三、分類彙總
分類彙總是彙總和排序兩個功能來進行分類和彙總的。按照排序的字段的值進行分類，對已經彙總的字段進行分類彙總。在設置排序的時候設置類型slis_t_sortinfo_alv－subtot ＝ ‘X’ 就可以了。
四、彙總
彙總是設置要彙總的字段的Fieldcat屬性，設置slis_t_fieldcat_alv-do_sum = ‘X’。
