Go into editor. Type the word "DATA". Place cursor within the word "DATA". Press F1.

Actually, before you even go near a SAP system, get a book about ABAP, or go on a training course, or at least read the help.

Using Predefined Types

1. DATA { {var[(len)] TYPE abap_type [DECIMALS dec]}

| {var TYPE abap_type [LENGTH len] [DECIMALS dec]} }

[VALUE val|{IS INITIAL}]

[READ-ONLY].

Reference to Existing Types

2. DATA var { {TYPE [LINE OF] type}

| {LIKE [LINE OF] dobj} }

[VALUE val|{IS INITIAL}]

[READ-ONLY].

Reference Variables

3. DATA ref { {TYPE REF TO type}

| {LIKE REF TO dobj} }

[VALUE IS INITIAL]

[READ-ONLY].

Structures

4. DATA BEGIN OF struc [READ-ONLY].

...

{DATA comp ...} | {INCLUDE {TYPE|STRUCTURE} ...}.

...

DATA END OF struc.

Internal Tables

5. DATA itab { {TYPE tabkind OF [REF TO] type}

| {LIKE tabkind OF dobj} }

[WITH key] [INITIAL SIZE n]

[WITH HEADER LINE]

[VALUE IS INITIAL]

[READ-ONLY].

Ranges Table

6. DATA rtab {TYPE RANGE OF type}|{LIKE RANGE OF dobj}

[INITIAL SIZE n]

[WITH HEADER LINE]

[VALUE IS INITIAL]

[READ-ONLY].

Hi,

Follow the code below.

----

types : begin of ty_ekko,

ebeln type ekko-ebeln,

lifnr type ekko-lifnr,

bsart type ekko-bsart,

aedat type ekko-aedat,

ernam type ekko-ernam,

end of ty_ekko.

end of ty_eket.

Creating internal table using predefined structure type

data : it_ekko type standard table of ty_ekko,

it_eket type standard table of ty_eket.

Creating internal table using predefined structure type

data : wa_ekko type standard table of ty_ekko,

hi ,

In the following way u can define

*types :  begin of ty_itab,*
           *a type i,*
           *b type i,*
          *end of ty_itab.     "-------> this is  a  structure.....*

*Data : wa_itab type ty_itab,  " -------> work Area ,*
          *it_itab type table of  ty_itab,  " -------> body*

* Data  : begin of ty_itab occurs 0,**
           **a type i,**
           **b type i,**
          **end of ty_itab.     "-------> this is  a  structure with headerline/work area and body.**
