Sure, check out section 2.3.12 File location object in the SAP Data Services Reference Guide (url as given before). The function you need is actually called copy_from_remote_system:
copy_from_remote_system(“flo_ftp_1”, “prod.txt”)
This function uses the FTP information in the file location object flo_ftp_1 to copy the file named prod.txt that is located in a remote directory.
