1. Create a link between SAP XI and EBP and SAP XI and SUS
2. If they are on the same client then your life is easy as you need to do the config only once. This is for activating your proxy.
3. Once you have done this you have to start doing config in the Integration directory for configuring the Interfaces. I did not get any specific guide for this.
Once you go through all the namespace, you will understand which interface is sender and which is receiver and then you can map the same. For you the sender and receiver would be the same as EBP and SUS are on the same client but it still has to go through XI.
Also, you can refer to this thread for EBP-XI-SUS:-
Hope this provided you some initial guide for settings.
Supplier Self-Services (SUS) is a solution that reduces the costs of procurement cycles by improving the exchange of business documents and shortening the time it takes to process the content of these documents. While purchasers use familiar methods to order goods and services, SUS integrates suppliers into the procurement process to a much larger extent.
Using SUS, suppliers do not need their own systems to supply goods and services, but have direct Internet access to the purchaser's procurement system via a Web browser. By this means, they are able to rapidly react to order functions received from the host.
You can use SUS with the following business scenarios:
SUS is installed separately, and configured to work together with SAP SRM as procurement system. From a technical aspect, this represents a standalone scenario with a Financial Accounting (FI) back-end system.
Plan-Driven Procurement with Supplier Integration
SUS is installed separately, and configured to work together with Materials Management (MM) as procurement system. This enables the procurement of direct materials. From a technical aspect, this represents a classic scenario with one or more MM back-end systems.
In both scenarios, purchasers can enhance their selected procurement system to grant suppliers access to SUS. Purchase orders, advanced shipping notifications (ASN), invoices, and evaluated receipt settlement (ERS) invoices (see the following sections) are transferred using the SAP Exchange Infrastructure (XI) by means of intermediate documents (IDoc) and XML messages.
