File archiving in application server ?

[Former Member]

Hi Experts,

How to a archive file in application server to another folder? Is there any function module used for that?.

Thanks

try using CG3Z transaction or use OPEN dATASET statement

Hi Dan,

you can use following syntax:

OPEN DATASET v_file FOR APPENDING IN TEXT MODE ENCODING DEFAULT.

IF sy-subrc <> 0.

MESSAGE text-002 TYPE 'I'.

ELSE.

CLEAR x_data.

LOOP AT it_data INTO x_data.

TRANSFER x_data TO v_file.

APPEND x_data TO it_sdata.

CLEAR x_data.

ENDLOOP.

ENDIF.

CLOSE DATASET v_file.

Or you can use Transaction Code CG3Z.

Hi,

You can request the Basis to do it. Else you can also write a small Unix Script to copy the file or move a file from one folder on the Application server to another.

This script will run in an ABAP program.

Hope this helps...

Hi,

Chk these two FMs:

C13Z_APPL_TO_FRONT_END

C13Z_FRONT_END_TO_APPL

One is to move from Appl.server to Front end, and another from front end to appl. server.

Go to Tcode: AL11 and decide the folder where you want to place the file.

There is no straight forward way to do it. You can use OPEN DATASET, READ DATASET, TRANSFER DATASET, DELETE DATASET to open the source file, read it into an internal table, transfer the contents of the internal table to the target file and then delete the source file.

You can also ask your unix administrators to simply provide you with a unix script that takes in the source and target directories and moves the file from source to destination. Once you have the script, you can create an external system command in SAP (SM69, SM49) which can be executed through an ABAP program by calling the function module SXPG_COMMAND_EXECUTE.

Hi Dan

For archiving, we can use FM: <b>EPS_DELETE_FILE</b> for archiving a file.

Below code can help you understand for moving a file:

[code]FUNCTION y_copy_file_within_appli_serv.
