ABAP：从现有数据库表创建内部表的语法 [英] ABAP: Syntax for creating internal table from existing database table

问题描述

我是ABAP的新手。开始学习内部表。我正在阅读创建内部表的方法。

I'm new to ABAP. Started learning about internal tables. I was reading on the ways to create internal tables.

我遇到了以下语法，从现有数据库表创建内部表：

I came across the following syntax to create an internal table from an existing database table:

data: it_mara type table of mara.

我很困惑，因为mara是一个表，并且如果lhs和rhs是同一类型，那么

I'm confused since mara is a table and if both l.h.s and r.h.s are of the same type then shouldn't it be just:

data: it_mara type mara.

当mara已经是表格时，需要将其转换为表格是什么？

What is the need to convert mara into a table when it is already a table?

推荐答案

MARA 是透明的表，这意味着它与结构类型 MARA 。这就是SAP的工作方式。 ：）

MARA is a transparent table which means that it functions at the same time as the structure type MARA. This is the way SAP works. :)
