Attachment transfer of PO from SRM to Back end for extended classic scenario

Hi Experts,

     We are using the SRM 7.0 with EHP 701 and ECC 6 , we have a SRM requirement where we need to transfer the attachment of a PO to back end ECC. I tried to implement the note 1594966 , but it doesn't work . we are using Extended classic scenario. Please suggest some SAP notes or the procedure to be followed to achieve this.

Thanks ,
