SAP MDG · REPLICATION OUTBOUND

How does a custom MDG outbound class for customer replication work in DRF and IDoc processing?

A custom MDG customer outbound class like ZCL_MDG_BS_CUST_ALE_DRF typically initializes the local business system, filters the replication scope, resolves BP/customer keys through MDG matching services, and then sends customer-related IDocs such as DEBMAS, ADRMAS, ADR2MAS, ADR3MAS, CLFMAS, and DOLMAS.

SOLUTION SUMMARY · SHORT ANSWER

A custom MDG customer outbound class like ZCL_MDG_BS_CUST_ALE_DRF typically initializes the local business system, filters the replication scope, resolves BP/customer keys through MDG matching services, and then sends customer-related IDocs such as DEBMAS, ADRMAS, ADR2MAS, ADR3MAS, CLFMAS, and DOLMAS.

`ZCL_MDG_BS_CUST_ALE_DRF` is a custom outbound implementation for MDG customer replication over DRF and IDoc processing. It inherits from `CL_MDG_BS_BP_SUPER_DRF`, implements `IF_DRF_OUTBOUND`, and coordinates identifier mapping, contact/assignment handling, scope filtering, and outbound IDoc creation.

Process flow

  1. Read `CONSTRUCTOR` to understand how the hub business system is initialized.
  2. Inspect `IF_DRF_OUTBOUND~INITIALIZE` and `IF_DRF_OUTBOUND~READ_COMPLETE_DATA` before changing any send logic.
  3. Review `GET_CUST_ID_FROM_BP_ID`, `GET_BP_ID_FROM_CUST_ID`, `READ_KEY_MAPPING`, and `WRITE_KEY_MAPPING` for identifier translation.
  4. Check `GET_VKORG_FILTER` and `GET_BURKS_FILTER` for outbound scope selection.
  5. Review `SEND_DEBMAS_IDOC` and the related `SEND_*_IDOC` helpers for payload creation and outbound messaging.
  6. Use `HANDLE_MULTI_OBJ_CLASSES` when the outbound object contains multiple assignment or classification objects.
  7. Validate `IF_DRF_OUTBOUND~SEND_MESSAGE` to ensure message/retry handling and object reporting are correct.
