This paper presents a novel architectural blueprint for embedding an adaptive intelligence layer integrated with SAP S/4HANA's Financial Accounting and Controlling (FICO) modules, with machine learning services hosted on SAP Business Technology Platform (BTP), to achieve automated confidence-aware cash application. The proposed design extends native S/4HANA workflows by integrating a machine learning service that interprets unstructured remittance data from multi-channel payment inputs including BAI2, ISO 20022, and IDoc formats, to probabilistically match incoming payments to open receivables. The architecture leverages Core Data Services (CDS) views for feature extraction and utilizes the SAP Business Technology Platform (BTP) as a runtime environment for model inference, ensuring governance and auditability through standard Fiori-based exception handling workflows. A simulation using anonymized historical payment data from a manufacturing context demonstrates that the simulation indicates an improvement in Days Sales Outstanding (DSO) and manual postings compared to static BRF+ rule sets, offering a scalable path to intelligent finance automation within the S/4HANA digital core.
