Why should an ERP-based MDG hub be converted to SAP S/4HANA, and what are the main prerequisites and impacts?
SAP strongly recommends converting ERP-based MDG hub systems to SAP S/4HANA because MDG capabilities in SAP S/4HANA 1809 already go beyond ERP-based MDG 9.2. The conversion must be treated as a standard S/4HANA conversion plus MDG-specific follow-up work for custom objects, simplification impacts, and material-number length behavior.

SAP strongly recommends converting ERP-based MDG hub systems to SAP S/4HANA. The guide is meant to complement the generic S/4HANA conversion guide and focuses on MDG-specific impacts such as custom code, custom objects, simplification-list items, customer/vendor integration, and material-number length behavior.
Process flow
- Determine the SAP ERP start release and supported conversion path.
- Plan the system conversion to SAP S/4HANA Core and, if necessary, migration to SAP HANA.
- Adapt the solution to SAP S/4HANA data structures and scope.
- Adjust custom code, MDG custom objects, and extensions.
- Migrate data where required to fit the new data model.
- Run the standard SAP S/4HANA conversion routines and checks.
- Review the SAP S/4HANA Simplification List.
- Check customer/vendor integration using the SAP S/4HANA Cookbook Customer/Vendor Integration.
