application server file downloading

[Former Member]

Hi Experts,

I have very urgent requiremnts for this :

1. The data extract needs to be downloaded on SAP application server ( take whatever path accessible to you).

2. Thereafter for every run, it should check if the file available in the same path and if yes then append data to this file instead of creating new one.

3. If file is not available then create new file.

please suggest me, how to do this.

it's very urgent

OPEN DATASET dsn FOR APPENDING. As it says in the help

"If the file specified already exists, it is opened and the file pointer is set at the end of the file. If the file specified does not exist, it is created"

Good, isn't it? You don't even have to write any logic.

hi,

use following logic

• Compile the file path

CONCATENATE text-t10 sy-datum c_txt INTO v_fname_out.

• Open the filepath on the application server for writing

OPEN DATASET v_fname_out FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.

• Check if the file could be opened

IF sy-subrc = 0.

• Loop at the internal table and transfer the contents to the file specified at the path

LOOP AT itab INTO wa.

TRANSFER wa TO v_fname_out FOR APPENDING.

CLEAR wa.

ENDLOOP.

ENDIF.

• Close the dataset

CLOSE DATASET v_fname_out.

Yes, but what if the file couldn't be opened?

Hi,

Open the file using 'OPEN DATASET ....'

Loop your internal table where in use command TRANSFER to transfer the contents of the file to application server.
