Version: 1.0 (2025)

1. Purpose

This Technical SOP provides a step-by-step execution guide for migrating legacy SAP ECC systems to SAP S/4HANA using SAP Activate. The procedure covers system preparation, technical conversion, custom code remediation, integrations, security hardening, data migration, automation, cutover, cyber controls, and hypercare operations.




2. Scope

This SOP applies to all systems in the SAP landscape:

  • SAP S/4HANA (Target System)

  • SAP Fiori

  • SAP GRC, IDM

  • Third-party interfaces (Non-SAP)

  • SAP Solution Manager or SAP Cloud ALM

  • SOC monitoring tools (SIEM, SOAR, SNOW, ARCS)

3. Roles & Responsibilities (RACI)

  • SAP Basis Team: Execute technical steps

  • SAP Security Team: Roles, SoD, Cyber Controls

  • DBA: HANA DB installation/upgrade

  • Functional Leads: Validation, testing

  • PMO: Governance, approvals

  • CISO/SOC: Security monitoring, audit validation

  • External SI Partner: Support during conversion

4. Tools Required

  • SAP Maintenance Planner

  • SAP Readiness Check

  • SUM (Software Update Manager)

  • SPDD/SPAU tools

  • ATC (Code Remediation)

  • SAP Fiori App Library

  • SAP SNOTE

  • SAP HANA Studio or Cockpit

  • Azure/AWS/GCP console (if cloud hosted)

  • SAP Solution Manager / SAP Cloud ALM



5. Pre-Migration Technical Checks

5.1 System Profiling

Run SAP Readiness Check 2.0

➡ Placeholder (Paste Screenshot Here):

Commands:

ST03N – Workload analysis
ST04 – DB performance
ST07 – SAP version details
SPAM – Support Package status
SM21 – System logs

5.2 Add-on & Business Function Analysis

Use Maintenance Planner to validate:

6.3 HANA Parameter Tuning

max_concurrency = 50
statement_memory_limit = 10GB

7. Custom Code Remediation

7.1 ATC Scan

Run:

ATC → Schedule Local Run → S4HANA Readiness

Output must include:

  • Syntax errors

  • Deprecated functions

  • Database dependency issues

  • Incompatible custom Z programs

9. SUM (Software Update Manager) Execution

9.1 Launch SUM

./SUMSTART confighostagent

9.2 Key SUM Phases

Phase 1: Extraction

Phase 2: Preprocessing

Phase 3: Execution

Phase 4: Postprocessing
