abap开发内表基础知识总结

1.定义一个结构体

DATA: BEGIN OF LS_MASTNR,

MATNR TYPE MATNR,

MAKTX TYPE MAKTX,

END OF LS_MATNR.

 

2.定义一个包含表头的内表

DATA: BEGIN OF LS_MAT OCCURS 0,

MATNR TYPE MATNR,

MAKTX TYPE MAKTX,

END OF LS_MAT.

 

3.参考数据结构来定义内表1

DATA: LT_MAT LIKE TABLE OF LS_MATNR WITH HEADER LINE.

 

4.参考数据结构来定义内表2

DATA:BEGIN OF LT_MATNR OCCURS 0.

INCLUDE STRUCTURE LS_MATNR.

DATA:END OF LT_MATNR.

 

5.常量定义

CONSTANTS:L_STR(10) TYPE C VALUE 'HELLO WORLD'.

 

6.RANGES 建立选择型内表

RANGES: R_MAT FOR MARA-MATNR.

 

DATA: BEGIN OF R_MAT OCCURS 0,
