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.

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.

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

  1. Receive the inbound proxy payload in the interface method.
  2. Read or create the MDG change request.
  3. Refresh the change request context for update scenarios.
  4. Validate inbound content before persistence.
  5. Write application or interface logs for errors and warnings.
  6. Update ERP or target-system data if required.
  7. Send a response or notification through the proxy interface.
