Bank Gl Consolidation Framework Using House Bank-Centric Design in Sap S/4hana

Abstract

The enterprise resource planning (ERP) systems with SAP S/4HANA were defined as the the primary financial processes for Bank General Ledger (Bank GL) management. Our review discusses the new framework of Bank GL consolidation through House Bank-focused design on SAP S/4HANA environment. The conventional SAP ECC systems maintained several GL accounts for each bank account and company code, resulting in complex reconciliation, and poor visibility into cash. S/4HANA can solve these inefficiencies by using single reconciliation GL account for the entire banking  which offers an integrated model of data that supports real-time financial reporting and integration of modules. In a critical analysis, the paper examines the architectural change to an object-oriented House Bank with centralized architecture with a discussion of its configuration, posting logic, reconciliation mechanism, and integration to embedded treasury functions, including Bank Account Management (BAM), Cash Management, and Bank Communication Management (BCM). The literature review and SAP documentation indicate such benefits as the decrease of GL volumes, better audit trails, and higher liquidity insights. There are, however, still difficulties in terms of complexity of transition, configuration risks, resistance within the organization and capability gaps amongst end-users. The review examines other toolsets, including SAP Activate, Readiness Check, and Transformation Navigator, and outlines future research directions in AI-driven reconciliation, API-based bank integration, and ESG-related financial reporting. The paper will add into the current discussion of the financial digital transformation by offering an in-depth analysis of the House Bank-oriented GL consolidation model that may be used by researchers and practitioners undertaking SAP S/4HANA finance implementations.
