Motivation for the NW 7.1 Architecture
SAP was motivated to address these constraints in the NW 7.1 release. SAP PI 7.1 is one example of a SAP solution that is available for general use using NW 7.1 architecture. Some of the key new architecture improvements with the NW 7.1–based SAP business applications are as follows:
• Separation of yet-to-be-processed user requests from in-process user requests by using fast channel architecture (FCA).
