SNC ASN creation via XML file

Hi all,

We have the PO collaboration scenario set up between ECC -XI- SNC.

We already have a process in place where our freight forwarder company transfers an XML file to our system(PI) and the ASN(IDOC)is posted to ECC.

Now with SNC,we need to do the same that is take the same file and post the XML ASN in SNC.

Can someone let me know how I can map the incoming XML file to create the ASN in SNC?

Also once the IBD is created in ECC,is there any information which needs to flow back to SNC?

Any inputs will be highly appreciated.

Thanks in advance.
