REST Receiver Adapter with Attachment as response?

Hi All,

We have a requirement (S4HANA<-->PI<-->ARIBA) synchronous scenario.

It is custom development where we send the request to Ariba and it returns the File as an attachment in response.

and place the file in AL11 of S4HANA server.

Below are my queries:

1) Currently we are in SAP PO SP 04 and I guess the attachment for REST adapter only supports from SP 07?

- Is there any alternative approach where we can do this without upgrading it to SP07?

2) How to read the File attachments in response and place it AL11 ?

Thanks

Sai
