S4H combines the data structures of different components (for FI, AA, CO, CO-PA and ML) into a single line item table ACDOCA, called as Universal journal. Aggregates are created dynamically based on line item table instantaneously (on the fly). There will be no aggregate (total), index and history tables in S4H.OLTP and OLAP capability in same system with real time reporting and predictive analysis.Hana’s column based tables provide faster access (as only affected columns need to be read in a query), better compression (due to few distinct values compared to rows), parallel processing (different columns can be easily processed parallely).

In-memory database means that data is read from memory i.e data always reside in main memory RAM (though Write happens in hard disk) and hence in-memory database reads data much faster w.r.t traditional databases (fetching the data from hard disk).Back bone of S4H’s design is with HANA’s in memory capability and below design principles S4H can only be run on Hana database unlike ECC which can be run on Oracle, IBM DB2 etc.
#SAP HANA VS SAP ECC FULL#
Trying to highlight the major(not a full list) differences in digital core of S4H as planned by SAP w.r.t ECC Most of us are following the innovations & simplifications in S/4 HANA and wondering about the functionalities & business benefits of implementing S/4 HANA (S4H).Find lot of questions on differences in ECC with S/4 HANA (S4H).
