SAP Exchange Infrastructure

Based on a native Web infrastructure that leverages open standards, SAP Exchange Infrastructure (SAP XI) makes it possible to manage the broad diversity of highly

heterogeneous components from a multitude of vendors and to run in various technology environments. The integration capabilities capture shared business semantics and act as a mediator between the services and their technical implementations. It includes technical functions, such as Web service discovery, queuing, mapping, and routing. It also establishes an infrastructure for business process management and high-performance execution within and across organizational boundaries.

Exchange-based process integration removes the problems of direct connections by extracting shared collaboration knowledge. These shared business semantics ease the integration of both external and internal components. Instead of directly coding point-to-point interfaces for each new component, the exchange infrastructure allows instant plug-in of new components once per component. This provides the flexibility needed in today’s

fast-changing business world, and it reduces integration costs compared to the direct connection approach.

4.2.2 SAP liveCache

SAP liveCache for SAP SCM

SAP liveCache is based on SAP DB technology and ensures the highest mySAP SCM performance. SAP liveCache is SAP's state of the art memory-based computing technology for real-time, high-speed processing of very large data volumes. The main capabilities of SAP's new memory-resident object oriented technology are the following:

• Application logic execution right where the data is stored in order to avoid network overload

• Aggregation of relational data structures retrieved from the database into application-specific optimized data representations in main memory. As a result, optimization and planning tasks can be performed in minutes or seconds.

• Built-in business functionality in the form of C++ object methods

• Semantic synchronization with the SAP database

• Ready to exploit 64-Bit technology

For more information about liveCache technology infrastructure, requirements, and

performance recommendations, see SAP Service Marketplace at service.sap.com/scm.

SAP liveCache is available on Windows 2000 (or higher) and on 64-Bit UNIX (as of SAP APO 3.0A).

LCA Routines for SAP SCM

ABAP programs and the SAP APO optimizers use native SQL for communicating through the standard SAP database interface to liveCache. SAP liveCache has an SQL interface that is

used to communicate with the SAP instances. With native SQL, ABAP programs call stored procedures in the SAP liveCache that point to Component Object Model (COM) routines written in C++. An SQL class provides access from the LCA routine (formerly known as COM routines) to the SQL data.

The LCA routines are part of a dynamic link library that runs in the process context of the SAP liveCache instance.

The LCA routines have direct access to the objects stored in the SAP liveCache and can change them. This includes creation and deletion of objects in the SAP liveCache.

This section provides an overview of which business process of mySAP SCM uses which component.

Please note that there are software requirements for each component below, which are not explicitly mentioned in this documentation. They are

documented in the relevant installation guides.

This Master Guide provides just one way to implement each business process. This is the implementation valid for SAP SCM 5.0.
