HA250 – Database Migration Using DMO – SAP HANA 2.0 SPS07 — Lesson 1: DMO Architecture, Prerequisites, and Project Readiness

Learning Objectives

• Explain how DMO Architecture, Prerequisites, and Project Readiness supports controlled DMO migration.
• Complete the workflow and produce a reviewable DMO readiness and migration strategy workbook.
• Evaluate the condition where the chosen source release is incompatible with the intended target stack and select a supported response.

Detailed Topics

• SUM and DMO process architecture: business purpose, responsible roles, and SAP objects that establish the operating scope.
• Supported source and target combinations: organizational assignments, master records, and dependencies required before processing begins.
• Sizing and downtime planning: navigation, field control, and status logic used to create a reliable starting point.
• Backup and fallback prerequisites: approval and evidence checkpoints that confirm the foundation is ready for use.

Instructor Demonstration

The guided walkthrough links SUM and DMO process architecture, Supported source and target combinations, Sizing and downtime planning, Backup and fallback prerequisites to business outcomes and control evidence. Learners see how the process should appear in SAP, what belongs in DMO readiness and migration strategy workbook, and how the team should respond when the chosen source release is incompatible with the intended target stack.

Hands-On Exercise

Complete a controlled activity covering SUM and DMO process architecture, Supported source and target combinations, Sizing and downtime planning, Backup and fallback prerequisites and preserve the final result in DMO readiness and migration strategy workbook.

1. Set the scope, roles, evidence requirements, and success conditions for the practical case.
2. Run the process or configuration steps and annotate the resulting records, statuses, and integration effects.
3. Challenge the result using the stated exception and distinguish symptom, cause, and downstream consequence.
4. Finalize the deliverable with correction evidence, approvals, escalation criteria, and measurable next actions.

Scenario Analysis

• Which SAP object, rule, master record, or process step most strongly influences the observed result?
• What evidence distinguishes a configuration problem from data, authorization, integration, or timing causes?
• How should the DMO readiness and migration strategy workbook be approved, retained, monitored, and updated after handover?

Troubleshooting Guidance

Start at the earliest point where expected SAP behavior differs from the observed result. Review process sequence, master data, organizational assignments, configuration, authorization, integration, and timing separately. Treat “the chosen source release is incompatible with the intended target stack” as a testable hypothesis until settings, documents, logs, reports, and retest outcomes confirm the cause.

Validation Checklist

• Required structures, master data, roles, settings, and dependencies for DMO Architecture, Prerequisites, and Project Readiness are present.
• The DMO readiness and migration strategy workbook connects each conclusion to objective, reviewable SAP evidence.
• Normal processing, the stated exception, integration behavior, and access boundaries were tested.
• Corrections, retest criteria, ownership, documentation, monitoring, and operational handover are complete.

Lesson Outcome

Learners can apply DMO Architecture, Prerequisites, and Project Readiness, explain the resulting SAP behavior, and defend the outcome through DMO readiness and migration strategy workbook.
