We have a client requirement for activating SUS functionality. The main objective is Suppliers should able to check their own Invoice Statuses which are created and posted in back end R/3.
We are using Extended Classic Scenario (SRM4.0 and ECC6.0).
My Doubts: I have come to know through some of my friends and SDN forums:
1. To check Invoice status in SUS portal, the Invoice should have originated from SUS. Then only it is possible to check/find status from SUS portal.
2. In Extended Classic Scenario, it is not possible to replicate PO's from R/3 to SUS portal.
3. Is it part of SAP standard Scenario or purely custom development would be required.
If above 2 points are true, is there any alternate solution available for SUS usage for Invoices while using ECS scenario.
