Summary of "17 - ABAP on HANA - Comparison of ECC , SOH and S4H Systems Part2"

Comparison of SAP System Types: ECC, SAP Business Suite on HANA, and S/4HANA

The video provides a detailed comparison and method to identify three SAP system types, focusing on their technological differences—especially regarding database and application layers.

Key Technological Concepts and Product Features

1. SAP ECC System

Uses traditional databases (e.g., Sybase).
Application layer is ECC (ERP Central Component).
Material number length in the MARA table is 18 characters.
Transaction codes like XD01 (create customer) and XK01 (create vendor) exist.
Product version shows SAP ERP 6.0 with enhancement packs (e.g., EP8).
Database type can be verified via System Status.

2. SAP Business Suite on HANA (SoH)

Application layer remains ECC.
Database switched from traditional to HANA (an in-memory database appliance combining hardware and software).
Material number length remains 18 in the MARA table.
Transaction codes XD01 and XK01 still exist.
Product version still shows SAP ERP 6.0, indicating ECC application layer.
System Status shows database as HANA.
Represents a hybrid where only the database is upgraded to HANA.

3. SAP S/4HANA System

Complete suite runs on HANA: both application and database layers are HANA-native.
Product version shows HANA release year (e.g., 2022), no longer SAP ERP 6.0.
Material number length in MARA table is extended to 40 characters, indicating application layer changes.
Traditional ECC transaction codes like XD01 and XK01 are obsolete; replaced by BP transaction code.
System Status shows database as HANA.
Represents a full modernization of SAP with in-memory technology and new application design.

How to Identify the System Type

Check System Status → Database type Determine if the database is traditional or HANA.
Check Product Version
- SAP ERP 6.0 indicates ECC or SoH.
- HANA version indicates S/4HANA.
Check MARA Table (using transaction SC11)
- Material number length 18 → ECC or SoH.
- Material number length 40 → S/4HANA.
Check Transaction Codes
- XD01/XK01 exist in ECC and SoH.
- Obsolete in S/4HANA, replaced by BP.

Summary

System Type Database Type Application Layer Material Number Length Transaction Codes Product Version ECC Traditional ECC 18 XD01, XK01 SAP ERP 6.0 + Enhancement Packs SAP Business Suite on HANA (SoH) HANA ECC 18 XD01, XK01 SAP ERP 6.0 + Enhancement Packs S/4HANA HANA HANA-native 40 BP (replaces XD01/XK01) HANA release year (e.g., 2022)

This guide helps SAP professionals quickly determine the system type by checking the database, product version, table structure, and transaction codes.
