FTP file transfer in Background

1) Creating RFC Destination for FTP.

Run program: RSFTP005.

The RFC destinations SAPFTP and SAPFTPA will be created automatically.

a) SAPFTP (for local system)

b) SAPFTPA (for running in Application server)(This is used for file transfer in background.

2) Code sample for developing FTP programs can be got from report program

a) RSFTP002

b) RSFTP007

c) RSFTP008

3) Sample code for getting customer details as tab delimited .TXT file in background.
