此语句的变体LOOP AT设置系统字段sy-tabix的值: ◾ 在索引表的每个循环中,以及在关联表索引中的当前表行的行号上使用排序键时,都会进行传递。 ◾ 在哈希表中以及对值0使用哈希键时。 LOOP AT不会修改sy-subrc。使用ENDLOOP离开循环后,sy-tabix设置为进入循环前的值,适用于sy-subrc: sy-subrc含义 0循环至...
If no appropriate rows are found or if the internal table is blank, the loop is not run at all. System Fields This variant of the statement LOOP AT sets the value of the system field sy-tabix: In each loop pass for index tables and when using a sorted key on the row number of ...
Example 2 – Usage of MEMBERS, SIZE and INDEX The 2nd phase of the GROUP BY is the access the members of the LOOP. To get the members of the group, we need to LOOP AT GROUP within the main LOOP. This inner LOOP needs to use the group result to get the members. The new BASE ad...

SAP Managed Tags: ABAP Development Hi, dependent on your version, you can select directly from an internal table like: select sum( d~hsl ) as HSL , d~BLART from @it_data as d group by d~BLART into table @data(lt_result) or data: lt_result type hashed table of xxx with unique...
嵌套哈希内表- AT NEW 语句 构造 两个排序表通过INDEX 优化 二分查找优化 三 先说结论 通过测试: 双排序表通过 index 优化的方式性能最优.(建议有经验的开发采用这种方式).但是该方式对数据有要求: LT_A 内表中的数据不能重复. 通常情况,建议采用二分查找后循环的方式. ...
