SAP Simple Finance provides an accounting solution powered by SAP HANA. It uses a Universal Journal that acts as a single source of transactional data for various modules like financial accounting, asset accounting, and profitability analysis. The Universal Journal replaces separate tables and indexes previously used by these modules and removes the need for reconciliation between modules. It stores transactional data in a single line item table with full details for all components. This provides benefits like multi-dimensional reporting without data replication and improved structural capabilities for the financial solution.
