在带有标题行的内部表上操作

Question

我有一个关于内部表的标题行问题。我给in_table1分配了一些值，然后尝试在下面的代码块中将APPEND命令添加到in_table2中的记录。但是我看不到我在in_table2中添加的记录。这是因为in_table2的标题行吗?如果是，我怎样才能看到记录呢?

Answer 1

首先，你不应该再使用带有header的内部表。

其次，如果你真的必须这样做，这里有一些解决方案。

标题in_table2在您的情况下当然是空的。你必须循环遍历表格才能打印出来。例如:

LOOP AT in_table2.   "here in_table2 means table (an internal table)
  WRITE / in_table2. "here in_table2 means the header of the table (a structure)
ENDLOOP.

由于这种混淆，不应该精确地使用带有头的内部表。看来你就是这样被弄糊涂了。in_table2的含义是模糊的，取决于上下文。

最好使用字段符号进行循环和追加。

FIELD-SYMBOLS: <fs_for_loop> LIKE LINE OF in_table2[].
LOOP AT in_table2[] ASSIGNING <fs_for_loop>.
  WRITE / <fs_for_loop>.
ENDLOOP.
