Hi Ali

You can try this logic,


DATA: V_COUNT TYPE I VALUE 1.

DO.

* Read Table 1
READ TABLE <I_TAB1> INTO <W_TAB1> INDEX V_COUNT.
* Append to Second Table
APPEND <W_TAB1> TO <I_TAB2>.

V_COUNT = V_COUNT + 1.
* limit is reached is then exit
IF V_COUNT > <No of Records>.
EXIT.
ENDIF.

ENDDO.

<b>You can find the code sample for downloading ot excel here</b>

Use this function module..

GUI_DOWNLOAD.

CALL FUNCTION 'GUI_DOWNLOAD'

EXPORTING

FILENAME = 'C:\TEST.XLS'

TABLES

DATA_TAB = IT.

first of all

declare the internal table (jtab) u want to fill from the internal table(big = itab ) with the fileds u want to append .

second to append the records u need to append like this.

loop at itab.
jtab-f1 = itab-f1.
jtab-f2 = itab-f2.
jtab-f3 = itab-f3.
jtab-f4 = itab-f4.

append jtab.
clear jtab.

endloop

this way u will fetch all the records into ur jtab with the desired fields.

third .to download this into an excel sheet .

use this fm .

DATA : v_length TYPE p.
p_pcfile will he the location to where u will drop the excel sheet .

declare this as 

parameters :  p_pcfile LIKE rlgrap-filename DEFAULT text-001 .

in the text  give the pathname this will do.

CALL FUNCTION 'WS_DOWNLOAD'
       EXPORTING
            filename   = p_pcfile          " ur path file .
            filetype   = 'DAT'                "this is for excel 
       IMPORTING
            filelength = v_length
       TABLES
            data_tab   = jtab.             " this is ur contents
*              fieldnames = it_fieldnames.

also u can use GUI_DOWNLOAD with the same effect.

vijay

Hi Ali

Excel has a limitation around 64 thousand records/rows.

Besides if you are planning to create multiple worksheets then you should opt for Excel ole.

The codes for the same are here,

http://www.sapdevelopment.co.uk/ms/ms_excel.htm

The logic is that after creating an Excel OLE object,

Loop into the internal table and start moving the contents to the sheet1 until 64K entries are reached as shown below


* Create first Excel Sheet
  CALL METHOD OF application 'Worksheets' = sheet
                               EXPORTING #1 = 1.
  CALL METHOD OF sheet 'Activate'.
  SET PROPERTY OF sheet 'Name' = 'Sheet1'.
  LOOP AT itab1.
    index = row_max * ( sy-tabix - 1 ) + 1. " 1 - column name
    CALL METHOD OF sheet 'Cells' = cells EXPORTING #1 = index.
    SET PROPERTY OF cells 'Value' = itab1-first_name.
  ENDLOOP.

Once it reaches the limit then you can add another sheet similarly as shown above and continues the same.

You just need to put a logic inside loop for creating the work sheets as you reach the 64K entries.

Hope this solves your problem.
