Hi,

How can we transfer the data to Internal table?

[Former Member]

hi

Use Select Statement to transfer values from table to Internal table.

example.

Select * from mara into table itab1 where matnr = P_matnr.

Reward me if its helpful.

hi,

If you know the table type, you should, for performance reasons, use the corresponding specific operation. For example, <b>you should use the APPEND[... TO statement to fill index tables, but INSERT ... INTO TABLE to fill hashed or generic tables.</b>

You can insert lines into internal tables either singly or in groups:

Inserting a Single Line

To add a line to an internal table, use the statement:

<b>INSERT <line> INTO TABLE <itab>.</b>

The following statement allows you to summate entries in an internal table:

<b>COLLECT <wa> INTO <itab>.</b>

<itab> must have a flat line type, and all of the fields that are not part of the table key must have a numeric type (F, I, or P). You specify the line that you want to add in a work area that is compatible with the line type.

for more information follow this link.

Hi,

There are several ways in which you can transfer data into internal table.

Eg:

data: begin of wa,

col1 type i,

col2 type i,

end of wa.

data itab like table of wa.

do 3 times.

wa-col1 = sy-index.

wa-col2 = sy-index ** 2.

append wa to itab.

enddo.

loop at itab into wa.

write:/ wa-col1,

wa-col2.

endloop.

Please Refer itab details in http://help.sap.com

Hakim

Hi Sivananda,

You can transfer data to internal table as follows:

<u><b>Transferring data from database to Internal table:</b></u>

select * from kna1 into table <b>i_kna1</b>

where kunnr = '0000000100'.

<b><u>Transferring data from Work area to Internal table:</u></b>

wa_kna1-kunnr = '101'.

wa_kna1-kunnr = 'aviva'.

append wa_kna1 to<b> i_kna1</b>.

wa_kna1-kunnr = '102'.

wa_kna1-kunnr = 'marko'.

append wa_kna1 to<b> i_kna1</b>.

Reward points for useful answers.

Hi sivananda,

This code will help you tranfer data to internal table.

1.DATA IS MOVING FROM ORIGINAL TABLE TO ITAB.

*****************************************************************

TABLES:EKKO.

DATA ITAB LIKE EKKO OCCURS 0 WITH HEADER LINE.

SELECT * FROM EKKO INTO TABLE ITAB.

2, DATA IS MOVING FROM DYNPRO SCREEN TO ITAB.

********************************************************************

TABLES: ZRFQ.

DATA ITAB LIKE ZRFQ OCCURS 0 WITH HEADER LINE.

ITAB-ASART = ZRFQ-ASART.

ITAB-SPRAS = ZRFQ-SPRAS.

ITAB-ANFDT = ZRFQ-ANFDT.

ITAB-ANGDT = ZRFQ-ANGDT.

ITAB-ANFNR = ZRFQ-ANFNR.

ITAB-EKORG = ZRFQ-EKORG.

ITAB-EKGRP = ZRFQ-EKGRP.

APPEND ITAB.

3.YOU CAN MOVE DATA DIRECTLY TO ITAB.

******************************************************

MOVE 10 TO ZRFQ-PINCR.
