ALV
标准功能汇总，分类汇总，排序，过滤这些功能除了可以直接使用它的标准功能按钮之外，你也可以在程序里设定，让ALV
列表第一次显示出来就已经使用了这些功能。
用REUSE_ALV_GRID_DISPLAY
实现的ALV
不能在程序设定输出字段的平均值，最小值，最大值等标准功能。用OO
方式实现ALV
输出的就可以，请参考

一、
排序
排序用到类型
slis_t_sortinfo_alv
，按条件把过滤的字段和规则设置好，添加到一个参考
slis_t_sortinfo_alv
类型的内表，在调用
Function
的时候指导内表赋给
it_sort
参数
二、
过滤
过滤用到类型
slis_t_filter_alv
，按条件把排序的字段和规则设置好，添加到一个参考
slis_t_filter_alv
类型的内表，在调用
Function
的时候把内表的值赋给
it_fitler
参数
三、
分类汇总
分类汇总是汇总和排序两个功能来进行分类和汇总的。按照排序的字段的值进行分类，对已经汇总的字段进行分类汇总。在设置排序的时候设置类型
slis_t_sortinfo_alv
－
subtot
＝
‘X’
就可以了。
四、
汇总
汇总是设置要汇总的字段的Fieldcat
属性，设置
slis_t_fieldcat_alv-do_sum
= ‘X’
。
