SAP is renowned for its ERP (Enterprise Resource Planning) software, having served businesses across the globe since 1972. The SAP ERP journey has evolved from R/1, R/2, and R/3 to SAP ECC and SAP S/4HANA, with SAP ECC being widely used in organizations worldwide today. However, SAP has announced that SAP ECC will no longer be supported after 2027, marking a significant shift towards its latest ERP solution, SAP S/4HANA. This blog will delve into the key difference between SAP ECC and SAP S/4HANA, their unique features, and the business benefits of upgrading.
What is SAP ECC?
SAP ERP Central Component (SAP ECC) is a modular ERP solution that allows businesses to optimize operations across various functions such as Finance, Logistics, HR, Product Planning, and Customer Service. Its flexibility enables businesses to customize and integrate the modules they need, though this flexibility can introduce complexities. Changes in one module can impact others, requiring meticulous testing before any updates or enhancements.
SAP has announced the end of maintenance for SAP ECC by 2027, urging businesses to migrate to SAP S/4HANA.
What is SAP S/4HANA?
SAP S/4HANA is SAP’s latest ERP solution, built on the powerful SAP HANA in-memory database. This ERP system processes transactional and analytical data in real time, offering a significant upgrade in terms of performance and speed compared to traditional systems. It also introduces a modern user experience with SAP Fiori, streamlining business processes and improving decision-making.
With more than 40,000 SAP ECC customers expected to transition to SAP S/4HANA by 2027, this system is poised to become SAP’s flagship ERP solution.
Key Differences Between SAP ECC and SAP S/4HANA
Universal Journal (ACDOCA) – A Single Source of Truth
Consolidates the data structures from Financial Accounting (FI), Asset Accounting (AA), Controlling (CO), CO-PA, and the Material Ledger into a single table, ACDOCA, also known as the Universal Journal. This eliminates redundant tables and significantly reduces data duplication, streamlining financial reporting.
MATDOC – New Line Item for Inventory Management
In SAP ECC, inventory management involved multiple tables like MKPF and MSEG. SAP S/4HANA simplifies this by introducing MATDOC, a single line item for all inventory transactions, eliminating the need for over 26 tables and improving efficiency in data processing.
In-Memory HANA Database
While SAP ECC supports third-party databases like Oracle and IBM DB2, SAP S/4HANA is exclusively designed for the SAP HANA database. HANA’s in-memory capabilities enable real-time data processing, faster query execution, and simplified data storage. It also merges Online Transaction Processing (OLTP) and Online Analytical Processing (OLAP) into one system, allowing real-time reporting and predictive analysis.
CO and FI Merger
In SAP ECC, General Ledger (GL) accounts are mapped to CO primary cost elements. SAP S/4HANA combines these into a single source, removing the need for reconciliations between CO and FI, speeding up period-end closing.
Business Partner as Mandatory
Unlike SAP ECC, where Business Partners were optional, SAP S/4HANA mandates that all customers and vendors be integrated as Business Partners. This standardization simplifies master data management.
Extended Material Number
SAP S/4HANA offers an optional feature to extend material numbers from 18 to 40 characters, giving businesses more flexibility in identifying materials, though careful planning is needed for its adoption.
Advanced Credit Management
In SAP ECC, credit management relied on manual processes through FI-AR-CR. SAP S/4HANA replaces this with FSCM (Financial Supply Chain Management), which automates credit risk scoring, master data updates, and workflows for credit approvals.
Real-Time MRP
SAP ECC’s Material Requirement Planning (MRP) required batch jobs, but SAP S/4HANA enables real-time MRP execution, eliminating the need for batch jobs and simplifying processes like subcontracting.
Global Trade Services (GTS)
SAP ECC’s foreign trade functionalities are replaced by SAP S/4HANA’s GTS, which automates processes like Sanctioned Party List (SPL) screening, embargo checks, and license verifications.
Mandatory Material Ledger
The Material Ledger, optional in SAP ECC, becomes mandatory in SAP S/4HANA. It allows businesses to track inventory in multiple currencies and apply multi-valuations, improving financial transparency.
Difference Between SAP ECC and SAP S/4HANA

Material Management | Requires multiple tables for inventory (MKPF, MSEG) | Simplified with MATDOC for single-line inventory transactions |
Credit Management | Manual through FI-AR-CR | Automated with FSCM (Financial Supply Chain Management) |
Real-Time Processing | Relies on batch jobs for data processing | Real-time processing with no batch jobs required |
Custom Code Adjustments | Requires manual changes | Compatibility views allow smooth transition of custom code |
Business Partners | Optional | Mandatory, simplifying master data management |
Material Ledger | Optional | Mandatory, allowing multi-currency and multi-valuation tracking |
MRP (Material Requirement Planning) | Batch job-based | Real-time MRP execution, eliminating the need for batch jobs |
Business Benefits of SAP S/4HANA
Migrating from SAP ECC to SAP S/4HANA delivers numerous benefits for businesses looking to optimize their operations and future-proof their ERP investments. Here’s a deeper look into the key advantages of moving to SAP S/4HANA:
Real-Time Business Insights
Processes data in real-time, allowing businesses to access live insights for faster decision-making. This feature helps companies react quickly to market trends and make more informed business decisions.
