Question 1

What is the difference between SAP ECC and SAP S/4HANA?

Accepted Answer

SAP ECC (ERP Central Component) is SAP’s previous-generation ERP platform running on traditional relational databases. SAP S/4HANA is the next-generation ERP built on the in-memory HANA database, enabling real-time analytics, simplified data models, and a modern user experience through SAP Fiori.

Question 2

When does SAP ECC maintenance end?

Accepted Answer

SAP mainstream maintenance for SAP ECC 6.0 has ended. Extended maintenance is available at an additional cost. Organizations should align their S/4HANA migration timelines with SAP’s support schedule to reduce operational and compliance risks.

Question 3

Should historical ECC data be migrated to S/4HANA?

Accepted Answer

In most cases, migrating large volumes of historical transactional data to S/4HANA is not recommended. It increases database size, licensing costs, and migration complexity without delivering proportional business value. A better approach is to archive historical data and maintain access through a separate archive system.

Question 4

What SAP data archiving objects are most important to archive before migration?

Accepted Answer

Key archiving objects include FI_DOCUMNT (financial documents), CO_ITEM (controlling line items), MM_MATBEL (material documents), SD_VBRK (billing documents), and PP_ORDER (production orders). Archiving these objects reduces database size and simplifies migration.

Question 5

How long must SAP financial data be retained after migration?

Accepted Answer

Retention requirements vary by jurisdiction, but financial records are typically retained for 7 to 10 years. Archived SAP data must remain accessible and auditable for the entire retention period, regardless of the originating system.
