Cannot Change an Internal Table in a Loop
You cannot change a complete internal table in a loop operating on this
table in ABAP Objects. Changes to the table as a whole may be caused
by, for example, the
REFRESH
, CLEAR , FREE , MOVE , SORT , or SELECT
INTO TABLE statements. This applies to internal tables from
procedures and internal tables imported
from a data cluster.
In ABAP Objects, the following statements cause an error message:
LOOP AT itab INTO wa.
CLEAR itab.
ENDLOOP.
Correct syntax:
LOOP AT itab INTO wa.
...
ENDLOOP.
CLEAR itab.
Cause:
When the table is accessed again, system behavior will be unpredictable
and may lead to runtime errors.
