SAP MDG · REPLICATION INBOUND
How does the standard SAP MDG inbound proxy pattern work for customer, vendor, STA, and supplier integrations, and what should I implement in a custom inbound proxy class?
SAP MDG inbound proxy classes typically accept the proxy payload, create or refresh a change request, validate the data, log issues, and then update ERP or send notifications. The custom `ZCL_SI_*` classes follow this same pattern, with dedicated helper methods for customer, vendor, STA, and supplier scenarios.

The custom `ZCL_SI_*` classes follow this same pattern, with dedicated helper methods for customer, vendor, STA, and supplier scenarios.
SAP MDG inbound proxy classes in the `ZCL_SI_*` family are designed to receive an external payload, translate it into MDG processing, validate the content, write logs, and then either update ERP or trigger follow-up notifications. The recommended pattern is to keep the proxy method thin and route the work into dedicated helper methods for change-request handling, validation, logging, and target-system update.
Process flow
- Receive the inbound proxy payload in the interface method.
- Read or create the MDG change request.
- Refresh the change request context for update scenarios.
- Validate inbound content before persistence.
- Write application or interface logs for errors and warnings.
- Update ERP or target-system data if required.
- Send a response or notification through the proxy interface.
