Material Attachment Migration SAP to SAP

Hi experts,

Maybe you can help me with a big challenge here. I need to migrate some materials attachment (MM03), these materials have been migrated from SAP to SAP systems and now I need to put them attachments massively. The two SAP systems are connected through RFC.

I used some FM as BDS_GOS_CONNECTIONS_GET and SO_DOCUMENT_READ_API1 to get the attachment in binary mode. So at this time I don’t know how to insert these attachments in another SAP system.

Find attached the details about the steps I’ve completed until now.

...after check the attachments

So, how to insert these attachments in the corresponding material through RFC? I did not find a GOS FM to insert it.

Thank you in advanced
