MIDDLEWARE RESILIENCE FRAMEWORK FOR SAP ECC-CRM INTEGRATION: DESIGN AND EVALUATION

For many enterprises, the integration between System Analysis Programs (SAP) Enterprise Resource Planning (ERP) (ERP Central Component (ECC)) and SAP Customer Relationship Management (CRM) systems through middleware is critical. However, this integration often encounters data synchronization failures and errors. In this paper, the challenge of building a resilience framework for managing SAP ECC–CRM incorporation problems, particularly those arising from asynchronous Business Document (BDoc) and Intermediate Documents (IDoc) message exchanges, is addressed. The proposed approach is designed to detect interface failures in real time, automatically retry transient errors, reconcile data mismatches betwixt systems, and alert support teams to critical problems. To recognize failures rapidly, a middleware architecture that integrates monitoring of SAP queues and error logs (e.g., SMW01 for CRM BDocs, Process Integration/Orchestration (PI/PO) logs, and ECC IDoc status records) is presented. As per the results, the resilience framework significantly improves integration reliability by auto-recovering from errors, maintaining data consistency, and diminishing manual intervention. As a result, the SAP middleware integration is more robust, leading to quicker error resolution, reduced business disruption, and almost full data synchronization between SAP ECC and CRM applications. Specifically, the framework achieved an estimated 80% improvement in average resolution time for errors and an overall reduction of 70% in manual reprocesses monitored in the test scenarios.
