CROSS-LEDGER STATE PROPAGATION AND CONVERGENCE MODELING FOR SAP FINANCIAL TRANSACTIONS OVER BLOCKCHAIN INFRASTRUCTURES

Abstract

Financial reporting within enterprise resource planning now commonly rides on a blockchain backbone, yet the problem of keeping each distributed ledger in sync remains stubbornly difficult-especially when SAP modules are at the controls. This paper describes a simulation-based testbed that watches SAP payment journals as they hop between differently configured blockchains, measuring how and when each copy reaches the same state. By replaying typical SAP routines under adjustable delay windows and choice of consensus rules, the model tallies the frequency of divergence, the lag before agreement, and the mechanics of clearing up disputes. Output files display convex 3D surfaces, animated heat maps, and step-by-step trails of how conflicts get settled; taken together, they point middleware designers toward tighter sync logic, smarter contract frameworks, and faster multi-ledger audits. In broader terms, the findings shrink the technical distance SAP users must traverse to achieve clean, traceable cross-chain accounting.
