hi,

this example will help you:

TYPES: BEGIN OF name,

title(5) TYPE c,

first_name(10) TYPE c,

last_name(10) TYPE c,

END OF name.

TYPES: BEGIN OF mylist,

client TYPE name,

number TYPE i,

END OF mylist.

DATA list TYPE mylist.

list-client-title = 'Lord'.

list-client-first_name = 'Howard'.

list-client-last_name = 'Mac Duff'.

list-number = 1.

WRITE list-client-title.

WRITE list-client-first_name.

WRITE list-client-last_name.

WRITE / 'Number'.

WRITE list-number.

declare an internal table and use this internal table ...

data : it_zmara like zmara occurs 0 with header line.

u have to create ITAB using structure STR.

data: ITAB type standard table of STR with header line initial size 0.

so that u can have internal table with same fields like STR.

Hi,

As you have created Z Structure, You need not to redeclare it in your program. You can directly create an internal table of type this structure or can use any field of the Structure as matnr-Zmara.

Hi,

you can use Structure in Type Declarations ,like you can define Internal Tables of this structure type,but you cannot Call a structure,and remember structure does not hold any data,its the Transparent tables that hold data.For more info on this you can refer ABAP Documentation.

yes neha

i know , structure dont have any values

but in many real time examples , they created many structures and from that structure they are fetching values.structure do have values at runtime right.thats why i'm asking.could you please help

sorry all, but all the answers are far away from perfectness...

if you have a structure (zmara) in the DB, you have to create internal table the following way:

DATA : itab TYPE TABLE OF zmara.

work area:

DATA : wa TYPE zmara

[Former Member]

You can't get data from Structure because it is a logical table & it willn't store any data. DB Table can store data if u want u can retrieve it. Just u can use structure during Runtime for referring some internal table's which r suppose to using in program thats it.

Through SE11...the structure which u have declared is global..

you can also declare structure internally also..SE38

Types : begin of str,

matnr type matnr,

werks type werks,

lgort type lgort,

end of str.

Then you need to declare internal tables...as follows...

Data : itab type standard table of str with header line.

or

data : begin of itab occurs 0.

include structure str / Zmara.

data : end of itab.

Then write the select query to retrive data from database table n then write staement..

its an simple ex to use structure in programs..
