SAP PI - Integration Scenarios
To create an integration scenario in SAP PI, you need to create technical and business system in System Landscape Directory.
The SLD is implemented as a Java software component (SAP _JTECHT) on the SAP NetWeaver Application Server Java. It is based on the open Common Information Model (CIM) standard, and is defined and published by the Distributed Management Task Force, Inc. at www.dmtf.org.
The SLD is the central listing tool for application component information, products and software components, and system landscape data (technical and business systems).
In SLD, to move from business model to technical model you use relationship between process step and software component.
How to Transfer Software Components in SLD?
When you install the System Landscape Directory, the initial catalog is installed.
From SAP Market Place, you can import more up to date catalog.
You can also import your own software components and products depending on the project and integration scenario.
For A2A scenarios, business systems are used and they exist in SLD. For B2B scenario, you use business objects and they reside in Integration Directory.
Technical systems are part of the System Landscape Directory (SLD) and contain information about version, database and patch levels, operating system, etc.
There are different modes on the technical system −
- AS ABAP System
- AS Java System
- Standalone Java system
- Third Party
There are different import tools that can be used to transfer data from the technical system to SLD. SAP NetWeaver Administrator is common SAP AS JAVA > 7.1 import tool.
Business system acts as a sender and a receiver in SLD. They inherit the software components from technical systems as products. No new software components can be added to the business systems in SLD.
With SAP AS ABAP, each client is defined as one business system. In SAP AS Java, each technical system acts as a business system.
