HA250 – Database Migration Using DMO – SAP HANA 2.0 SPS07 — Lesson 3: DMO Execution, Downtime, and Error Recovery

Learning Objectives

• Explain how DMO Execution, Downtime, and Error Recovery supports controlled DMO migration.
• Complete the workflow and produce a reviewable DMO execution and issue-resolution workbook.
• Evaluate the condition where a migration phase stops after partial table transfer with inconsistent restart evidence and select a supported response.

Detailed Topics

• Migration phases and logs: document sequence, decision points, and handoffs required for correct transaction execution.
• Downtime optimization options: determination logic and master-data influences that shape the resulting SAP document flow.
• R3load and migration monitoring: status changes, confirmations, messages, and operational evidence produced during processing.
• Controlled repeat and recovery actions: exception paths and recovery choices needed when normal processing cannot continue.

Instructor Demonstration

The instructor traces Migration phases and logs, Downtime optimization options, R3load and migration monitoring, Controlled repeat and recovery actions through the course scenario, explaining navigation, decision logic, dependencies, system messages, and the evidence retained in DMO execution and issue-resolution workbook. The walkthrough also shows how to investigate the condition where a migration phase stops after partial table transfer with inconsistent restart evidence.

Hands-On Exercise

Complete a controlled activity covering Migration phases and logs, Downtime optimization options, R3load and migration monitoring, Controlled repeat and recovery actions and preserve the final result in DMO execution and issue-resolution workbook.

1. Review prerequisites, process boundaries, master data, authorization, and acceptance criteria.
2. Complete the configured or transactional activity and preserve the resulting document and status trail.
3. Compare the normal result with the controlled exception and identify the most defensible root cause.
4. Record the selected response, validation result, residual risk, responsible owner, and review trigger.

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 execution and issue-resolution 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 “a migration phase stops after partial table transfer with inconsistent restart evidence” 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 Execution, Downtime, and Error Recovery are present.
• The DMO execution and issue-resolution 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 Execution, Downtime, and Error Recovery, explain the resulting SAP behavior, and defend the outcome through DMO execution and issue-resolution workbook.
