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，
<!--[if !supportLists]-->一、<!--[endif]-->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
<!--[if !supportLists]-->二、<!--[endif]-->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
<!--[if !supportLists]-->三、<!--[endif]-->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。
<!--[if !supportLists]-->四、<!--[endif]-->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’。
