SAP S/4 Hana and ECC – Differences


Introduction to the new S/4 HANA

  • Fourth version of SAP Business Suite, a future-ready digital platform
  • Built to solve complex queries and manager larger amount of data
  • Introduced a universal journal – ACDOCA combining reports and tables within a single dB
  • OLTP and OLAP functionalities within the same system, thereby enabling near real-time reporting and predictive analysis
    • OLTP helps with fast processing as OLTP dB are updated frequently.
    • OLAP relates to response time for complex queries to fetch a large amount of aggregated data from the dB for analytics or any related purposes.
    • [A good information can be gathered for OLTP and OLAP from this URL: https://www.stitchdata.com/resources/oltp-vs-olap%5D
  • Data retrieval is from HANA dB (in-memory) directly
  • New, enhanced and improved UI for touch-screens and mobile devices with UI5 applications
  • UI5 based Data Migration Workbench/Cockpit
  • Introduction of interactive reports using Fiori applications

Below is the table containing some points of comparison between S/4 HANA and ECC systems.

ECCS/4 H
Legacy UI as primary interfaceFeature-rich UI
Any 3rd party dB can be used such as Oracle, IBM DB2. Data is traversed using row-based approach.Improved performance planning, execution, report generation and analysis by using HANA dB as primary dB. The S4H uses column-based approach to traverse the data, thereby improving the performance of the data overall.
Legacy Warehouse management or third-party WMS integrationExtended Warehouse Management or EWM support for enhanced WM capabilities
Less tight integration with third-party apps, thereby increasing total cost of ownership for complete landscapeReduced total cost of ownership and data footprint with simplification of IT landscape
No concept of real-time inventory visibilityReal-time insights
Third-party omnichannel order management systems required to be usedAvailability of omni-channel for delivering value
Different customer and vendor master dataBusiness Partner has been made primary for customer and vendor
LSMW tool used primarily for data migrationLTMC is the new user-friendly data migration cockpit
No mandate of using material ledgerMaterial Ledger has been made mandatory with the introduction of Universal Journal
Multiple tables for storing different inventory management dataInventory management reduced to a single good table – MATDOC
Article/Material character length limited to 18 charactersArticle/Material length can be up to 40 characters
Header-level and item-level tablesNew line-item only tables
SAP Retail Store for in-store appsFiori-based MIM apps for store operations
Legacy merchandise and assortment planningSAP Merchandise planning and Assortment planning based on CAR
SAP AFS as a different solution overallSAP AFS and its applications are integrated within S4H system
No provision of using OLAP within the systemEnables use of OLAP within same system, thereby enabling real-time reporting and predictive analysis
No concept of universal journalACDOCA –  a universal journal introduced to store data from multiple tables, thereby reducing dependency on multiple tables
Company code currency has local currency as one end up to 2 parallel currencies onlyConcept of Parallel Currencies allow eight freely define able currencies in the universal journal table in addition to fixed (local as company code currency and global as controlling area currency)
GL accounts are map to controlling elements separatelyThe GL accounts and cost of elements are residing in this single Field of universal journal – ACDOCA
Traditional costing-based CO-PA required reconciliations between CO-PA and GLAccount based CO-PA is the default option while costing based CO-PA is now available as an option
