SAP MDG · REPLICATION OUTBOUND
How do I implement or extend proxy-based outbound MDG BP/customer replication in `ZCL_MDG_BP_CUSTOMER_PROXY_DRF`?
`ZCL_MDG_BP_CUSTOMER_PROXY_DRF` is a custom DRF outbound class for MDG BP/customer replication. It initializes runtime state, prunes non-replicable objects in `IF_DRF_OUTBOUND~READ_COMPLETE_DATA`, applies node-level filters, and sends the payload through the BP proxy/service layer in `IF_DRF_OUTBOUND~SEND_MESSAGE`.
SOLUTION SUMMARY · SHORT ANSWER
`ZCL_MDG_BP_CUSTOMER_PROXY_DRF` is a custom DRF outbound class for MDG BP/customer replication. It initializes runtime state, prunes non-replicable objects in `IF_DRF_OUTBOUND~READ_COMPLETE_DATA`, applies node-level filters, and sends the payload through the BP proxy/service layer in `IF_DRF_OUTBOUND~SEND_MESSAGE`.
`ZCL_MDG_BP_CUSTOMER_PROXY_DRF` is the proxy-based custom outbound implementation for MDG BP/customer replication. The main implementation flow is: initialize runtime state, filter out non-replicable records in `READ_COMPLETE_DATA`, apply node filters for content eligibility, and delegate sending to the BP proxy/service layer in `SEND_MESSAGE`.
Process flow
- Use `CONSTRUCTOR` or `CLASS_CONSTRUCTOR` to cache the local runtime state.
- Implement `IF_DRF_OUTBOUND~INITIALIZE` to create the instance and return metadata.
- Implement `IF_DRF_OUTBOUND~READ_COMPLETE_DATA` to suppress duplicates, employees, and other non-replicable objects.
- Apply governance-scope preparation before outbound dispatch.
- Use node filter helpers to control which BP subnodes are eligible for mapping.
- Implement `IF_DRF_OUTBOUND~SEND_MESSAGE` to delegate payload sending to the BP proxy/service layer.
- Raise a DRF exception for unrecoverable send-path errors.
