1、插入内表行:
*插入内表行:
DATA: BEGIN OF man,
name(20) TYPE c,
high TYPE p DECIMALS 2,
weight TYPE p DECIMALS 2,
END OF man.
DATA: man1 LIKE TABLE OF man.
man-name = '张参'.
man-high = '1.68'.
man-weight = 120.
INSERT man INTO TABLE man1.
man-name = '刘志'.
man-high = '1.78'.
man-weight = 160.
INSERT man INTO TABLE man1.
LOOP AT man1 INTO man.
WRITE: / man-name,man-high,man-weight.
ENDLOOP.
ULINE.
man-name = '钱华'.
man-high = '2.22'.
man-weight = 220.
INSERT man INTO man1 INDEX 3.
LOOP AT man1 INTO man.
WRITE: / man-name,man-high,man-weight.
ENDLOOP.
ULINE.

data_tab = man1
EXCEPTIONS
invalid_filesize = 1
invalid_table_width = 2
invalid_type = 3
no_batch = 4
unknown_error = 5
gui_refuse_filetransfer = 6
OTHERS = 7.
IF sy-subrc <> 0.
* message id sy-msgid type sy-msgty number sy-msgno
