ECC 6.0 includes several improvements over ECC 4.7 including new data storage in a single FAGLFLEXT table, real-time document splitting and integration between management and financial accounting, and cost of sales accounting with more flexible drill-down reporting. Major differences include the addition of parallel and special purpose ledgers, online derivation in profit centers, and changes to the debugger interface. The new GL concept separates data into leading and non-leading ledgers to improve data quality and reconciliation between cost of goods sold and financial accounting.
