How to transfer sap document to file server using FTP

I have successed.But my solution is foolish.

1st: CL_CRM_DOCUMENTS=>GET_WITH_TABLE

( The file of 'CL_CRM_DOCUMENTS=>GET_WITH_FILE' is on my PC ,not on SAP server )

2nd: Save the file table to a SAP server file.

(open dataset mode BINARY)

3nd: Transfer file by ftp command.

Can we do it easy.

Thanks.
