Program ID in Sender RFC adapter.

Hi Experts,

I have created 9 interfaces between same R3 (RFC Sender) and FTP (file receiver)server. ,

Do i need to create 9 RFC sender communication channels with different program ID (for registered server program in RFC destination type TCP/IP in R3), now i have created 9 RFC destination. is it possible for me to create single RFC destination with one program id for all the RFC sender interfaces.

thanks for your help
