Attachment in MM-SUS Scenario

Dear All,

In Classic Scenario

We have client's requirement to exchange documents between MM to SUS systems,

1. Attachment in ASN to Inbound delivery

2. Attachment from SUS Invoice to Invoice parked in ECC system.

SAP has shared custom solution for ECC PO to SUS PO but not for above points.

Please confirm or share if any solution available.

Best Regards

Ravi Panwar
