File Transfer with SFTP from ABAP

Hello Gurus,

We have a requirement that our client is migrating one of the EDI suppliers to other vendor who requires SFTP mechanism. The data transfer has to be done from ABAP system to other external system. We are not sure how we can accomplish this requirement. Can anyone share your ideas or thoughts on this?

If I am sure as of now they are transferring data with RFC. Now they want to move for SFTP.

What can we do from BASIS perspective?

Best Regards,

Amarnath
