Hello,

It depend on ur requirement wether to declare work area or internal table completely.

Hi,

If u decalre internal table with header no need to declare work area.

internal table with header:

data: itab like mara occurs 0 with header line.

internal table with out header:

data: itab like mara occurs 0.

data: wa type itab. (Work area).

It is always advisable to use workarea.

Plz mark if useful

HI,

if you are declaring with syntax, <b>data: begin of itab.</b>

or with header line then you don't need to declare.

otherwise you have to.

From 4.7 it is recmended to declare with header line. and use of workarea.

Hi,

Yes , you have to declare work area if not using OCCURS while declaring internal table.

hi vijaya,

to make more claer.

look this.

data : itab like ztable occurs 0 with header line.

here work area and itab is created.

data : begin of itab,

age like ztable-age,

endof itab.

only itab is created , no work area.

data : begin of itab <b>occurs 0</b>,

age like ztable-age,

endof itab.

here itab and work area is created.

types: begin of ty_itab,
field1,
field 2,
end of ty_itab.

data: itab type standared table of ty_itab.-->internal table without header line.
data: wa_itab like line of itab.--->work area

Hi!

Yes you are right! It is advisable to make a seperate Work area declaration as 'OCCURS' is Obsolete now.Typically as shown by Krishna Negi.

Hello,

OCCURS is not obsolete. But suggestion is that don't use that. Instead go for types and then declare your internal table as below,

TYPES: BEGIN OF TY_MARA,

MATNR TYPE MATNR,

MTART TYPE MTART,

lv_xx TYPE c,

ENDOF TY_MARA.

DATA: lwa_mara type ty_mara, (Work Area)

lt_mara like standard table of lwa_mara.

(Int. tabel)
