Edit a text file

[former_member194099]

Hello,

Is there a way in ABAP to open a text file kept on presentation server and then programatically edit it?

There are two functions GUI_UPLOAD and GUI_DOWNLOAD, but they fetch the data from file in form of table!!

Hi

What do you want to do?

Hi Sagar,

after you have loaded you file in the internal table, if I understood your problem, you can write on screen (write command) each record enabling the input mode.

In this way you could modify the text.

In other word you can build an interactive report, where you write only the file in the internal table.

I hope it can help you.

Hi Amit,

Your program partly solves the problem!!

After I upload a file to internal table(itab), I need to edit it programatically and not through a manual editor.

I have to replace certain words in the text file actually.

So after I execute my report I should get an updated text file.

So instead of EDITOR-CALL can I go and replace some text in itab??

Thanks lot for your help.

With Regards

Hi again,

1. yes.

Loop at the internal table.

use keyword

REPLACE (just see F1 help)

and accordingly modify the internal table.

Then finally use GUI_DOWNLOAD.

This will solve ur requirement.

Hi

You need to manage the string you've loaded in an internal table:

CALL FUNCTION 'GUI_UPLOAD'

............

TABLES

DATA_TAB = T_FILE.

LOOP AT T_FILE.

REPLACE 'HELLO' WITH 'BYE BYE' INTO T_FILE.

MODIFY T_FILE.

ENDLOOP.

CALL FUNCTION 'GUI_DOWNLOAD'

............

TABLES

DATA_TAB = T_FILE.
