to access a internal table you always need a work area whether implicit or explicit that is with header line or without header line.

refer to the link below:

hi,

in case of Loop At to an internal table you need to use work area.

however you may not use Explicit Work area if you work with Internal table with header line.

In that case the syntax will be

LOOP AT itab.
.......
.......
ENDLOOP.

here one work area having same as that of the internal table is created inplicitly.

create an explicit work area like internal table .

loop at itab into wa_area

write: wa_area-fields,

..........

endloop.

Hello

You can use a field-symbol instead:


FIELD-SYMBOLS: <ls_record>     TYPE ANY.

LOOP AT itab ASSIGNING <ls_record>.
...
ENDLOOP.

Hi.

What you actually want is this:

LOOP AT itab TRANSPORTING NO FIELDS.

.....

ENDLOOP.

This syntax does not require any workarea.

Hi ,

you can loop an internal table without an workarea by using field-symbols.

FIELD-SYMBOLS: <ls_record> TYPE ANY.

LOOP AT itab ASSIGNING <ls_record>.

...

ENDLOOP.

the field symbol acts an an counter to the internal table. the field symbol can also be declared as the type of the internal table.
