SAP ABAP结构与内表的创建

一、定义一个结构体

DATA:BEGIN OF LS_MATNR,
    MATNR TYPE MATNR,
    MAKTX  TYPE MAKTX,
END OF LS_MATNR.

二、定义一个包含表头的内表

DATA:BEGIN OF LT_MAT OCCURS 0,
    MATNR TYPE MATNR,
    MAKTX  TYPE MAKTX,
END OF LT_MAT.

三、参考数据结构来定义内表

DATA:LT_MAT LIKE TABLE OF LS_MATNR WITH HEADER LINE.

四、参考数据结构来创建内表

DATA:BEGIN OF LT_MATNR OCCURS 0.
    INCLUDE STRUCTURE LS_MATNR.
 END OF LT_MATNR.
