1. Introduction

The Direct Transfer approach in SAP S/4HANA Migration Cockpit enables real-time migration of data from one S/4HANA system to another without intermediate files or staging tables.

2. Technical Architecture

Direct Transfer utilizes ODATA services and Remote Function Calls (RFCs) to facilitate data migration between SAP S/4HANA systems.

3. Prerequisites

• Source System: SAP S/4HANA 1809 or later.
• Target System: SAP S/4HANA 1909 or later.
• ODATA services and RFC connections must be configured.

4. Step-by-Step Execution

1. Access the Migration Cockpit from SAP Fiori.
2. Establish source system connectivity.
3. Select migration objects and validate mappings.
4. Execute data extraction, validation, and import.

5. Advanced Configurations & Customization

Migration objects can be customized using Migration Object Modeler (LTMOM) to add or map additional fields.

6. Common Issues & Troubleshooting

Issue	Cause	Solution
ODATA Service Not Found	Service not activated	Activate in /IWFND/MAINT_SERVICE
No Data Retrieved	RFC connection issue	Check SM59 for connectivity errors

7. Key Benefits

• No intermediate file handling.
• Real-time data transfer reduces errors.
• Predefined migration objects simplify the process.

8. Conclusion

The Direct Transfer approach offers an efficient, secure, and automated way to migrate data between SAP S/4HANA systems, minimizing downtime and ensuring high data integrity.
