在ALV提供的标准工具栏上我们可以实现输出结果的聚合（最大值，最小值，汇总，平均数），排序，过滤功能，同样在程序里也可以达到这些功能。 <!--[if !supportLists]-->1. <!--[endif]-->声明聚合，排序，过滤所需要的变量。 DATA: lr_aggregations TYPE REF TO cl_salv_aggregations, lr_filters TYPE REF TO cl_salv_filters, lr_sorts type ref to cl_salv_sorts.
<!--[if !supportLists]-->2. <!--[endif]-->汇总
lr_aggregations->add_aggregation( columnname = 'DISTANCE' aggregation = if_salv_c_aggregation=>total ).
<!--[if !supportLists]-->3. <!--[endif]-->最小值
lr_aggregations->add_aggregation( columnname = 'FLTIME' aggregation = if_salv_c_aggregation=>minimum ).
<!--[if !supportLists]-->4. <!--[endif]-->过滤
lr_filters->add_filter( columnname = 'CITYFROM' sign = 'I' option = 'NE' low = 'ROM' high = '' ).
<!--[if !supportLists]-->5. <!--[endif]-->排序
lr_sorts->add_sort( columnname = 'CITYFROM' sequence = if_salv_c_sort=>sort_down subtotal = 'X' obligatory = 'X' ).
下面是程序的所有代码:
