Created: November-22, 2018

LOOP AT itab INTO wa.
ENDLOOP.

FIELD-SYMBOLS <fs> LIKE LINE OF itab.
LOOP AT itab ASSIGNING <fs>.
ENDLOOP.

LOOP AT itab ASSIGNING FIELD-SYMBOL(<fs>).
ENDLOOP.

LOOP AT itab REFERENCE INTO dref.
ENDLOOP.

LOOP AT itab TRANSPORTING NO FIELDS.
ENDLOOP.

有条件的循环

如果只有符合特定条件的行应该进入循环，则可以添加 WHERE。

LOOP AT itab INTO wa WHERE f1 = 'Max'.
ENDLOOP.
