Our client is replacing their existing middleware with SAP PO. One of the things they are missing out is that middleware's capability to double up as an FTP service. In their landscape, they have some systems that are directly uploading the files into the middleware. Now that we will be using SAP PO, we have asked them to install SFTP service at their end, so that SAP PO's SFTP adapter can send and receive files. Now we are being asked why can't we install SFTP service on SAP PO system, so that they can directly push the files.
As a SAP PO consultant, I know that this is not the best practice. The middleware is not supposed to be used as a file host/server.
But I am looking for a document to support by argument. I googled for it but couldn't find any.
Can anyone please give links to any documents/articles which talks about this point?
Thanks in advance,
Regards,
