Cannot Use Short Forms in Line Operations
In ABAP Objects, the following statements cause an error message:
Operations for all table types
INSERT TABLE itab.
COLLECT itab.
READ TABLE itab ...
MODIFY TABLE itab ...
MODIFY itab ... WHERE ...
DELETE TABLE itab.
LOOP AT itab ...
Operations for index tables
APPEND itab.
INSERT itab ...
MODIFY itab ...
Correct syntax:
Operations for all table types
INSERT wa INTO TABLE itab.
COLLECT wa INTO itab.
READ TABLE itab ... INTO wa | ASSIGNING <fs>.
MODIFY TABLE itab FROM wa ...
MODIFY itab FROM wa ... WHERE ...
DELETE TABLE itab FROM wa.
LOOP AT itab INTO wa ... | ASSIGNING <fs> ...
Operations for index tables
APPEND wa TO itab.
INSERT wa INTO itab ...
MODIFY itab FROM wa ...
Cause:
The reasons for this lie in the unambiguous separation of tables from work areas. This makes programs easier to read. Since you can declare tables without a
header line only in classes, this is only a constraint in local classes when accessing global tables in the
main program.
