需要构造一个哈希嵌套表,可以通过 GROUP BY 语句构造, 也可以用AT NEW 构造. 逻辑比较复杂, 性能较好 (通过AT NEW 构造比通过GROUP BY 语句构造性能更好 ),但是构造耗时较长. 04 排序表按INDEX 优化 该方式需要对两个内表都排序, 性能最好, 代码逻辑有点复杂. 并且有使用限制,LT_A-F1内容不能重复(如
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...
LOOP AT itab FROM idx1 TRANSPORTING NO FIELDS WHERE table_line > 60. DATA(idx2) = sy-tabix - 1. EXIT. ENDLOOP. DATA output TYPE TABLE OF i WITH EMPTY KEY. LOOP AT itab FROM idx1 TO idx2 INTO DATA(number). output = VALUE #( BASE output ( number ) ). ...
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...
LOOP AT IMAKT. MODULE SET_LINE_COUNT_0901. ENDLOOP. //程序 module SET_LINE_COUNT_0901 input MODIFY IMAKT index ctrl1-current_line. endmodule. 再说表格控制器 1.在layout中设置的表格控制器和.net中的gridview有点类似,其中的各个列必须和要和与之关联的内表的字段名称一样,否则将无法访问,或者是置...

I have a table node that pulls from two different internal tables. How can I loop through each table at the same time? I was going to loop through the main table in the table node then use the index (now a counter) as the loop criteria for the second internal table (in a loop nod...
SAP Managed Tags: ABAP Testing and Analysis "In the case of for all entries/loop the first two parts need to be done in the same way". I'm sorry, but it's not "in the same way". If you are doing a non-index search on the second table, retrieving the second table can be ...
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...
