USING KEY keyname is used to determine the table key with which the loop is executed. The table rows to be read in a LOOP loop can also be limited using optional conditions. If no conditions are declared, all table rows are read. ...

如果在USING key之后没有指定明确的表键名称,则读取行的顺序取决于表类别,如下所示: ◾ 标准表和排序表 通过主表索引中的行号升序读取行。在每个循环过程中,系统字段sy-tabix包含主表索引中当前行的行号。 ◾ 哈希表 行按照插入表中的顺序以及语句sort后使用的排序顺序进行处理。在每个循环过程中,系统字段sy-...

Many of you already know to work with For loop in SAP ABAP. However, those who are new to the ABAP 7.4 syntax often struggle at some places to achieve the expected result using new syntax. One of the scenario, I am covering below so that new learner can find help with this post. Sc...
Before the additional components can be declared, a group key binding must be defined in the output behavior group_result. The additional components can be accessed in the group loop using the data object or field symbol specified here.
