CRM middleware manages the delivery of configurable business object data from senders to multiple receivers. It provides major benefits like open architecture, efficient data distribution, role-based authorization, and error handling. The mySAP CRM solution can integrate with SAP R3 and non-SAP backend systems, with or without mobile sales or SAP BW integration. The CRM middleware consists of a core server, R3 plugin, communication station, and connection handler to control centralized message flow and conversion between systems.
