摘要：
排序也是ALV中的一个重要功能。当有总计时（请参阅--˃SALV教程11-聚合应用程序-总计、小计、平均值），排序可以实现排序字段的小计具体实现方法：1.Get_Sort方法获取CL_SALV_类对SORTS的引用，2，通过adding_Sort方法添加排序字段。如果需要小计，请输入参数小计
排序在ALV中也是一个比较重要的功能，在有合计(参照-->SALV教程11-Aggregations应用-合计(total)、小计(subtotal)、平均值(average))的场合下，排序能实现排序字段的小计(subtotal).
具体实现方法：
1，通过get_sorts方法得到类CL_SALV_SORTS的引用，
2，通过add_sort方法添加排序的字段，如果还要小计，输入参数subtotal就要传入’X'

运行，按销售订单号升序排序，并且每个订单有小计，
以上。
