SAP MDG · REPLICATION INBOUND
How does an SAP MDG inbound proxy for customer creation validate input and create the customer record?
The inbound customer creation method first validates request, customer number, and country through `zcl_mdgc_online_store_util->validate`, then loads sales/company constants, checks destination mapping in `zmdg_os_repmap`, and finally calls `zcl_mdgc_online_store_util->create_v2` to create the customer. If validation or destination mapping fails, it returns the error message immediately.
The inbound customer creation method first validates request, customer number, and country through `zcl_mdgc_online_store_util->validate`, then loads sales/company constants, checks destination mapping in `zmdg_os_repmap`, and finally calls `zcl_mdgc_online_store_util->create_v2` to create the customer. If validation or destination mapping fails, it returns the error message immediately.
The inbound customer creation proxy follows a simple gate-and-create pattern: it first reads the request payload, populates the output header, validates `req_id`, customer number, and country, then enriches the request with company/sales constants before calling the create routine. If validation fails or destination mapping is missing, it returns the error immediately.
Process flow
- Read `input-mt_dct_customer_create_request` into `ls_customer` and initialize `ls_output`.
- Set response control fields and copy the requested customer number.
- Call `zcl_mdgc_online_store_util->validate` with request ID, customer number, and country.
- Proceed only if validation returns type `S`.
- Map inbound fields to local variables for company, address, tax, and sales data.
- Derive company-code and sales-area defaults from `ls_tvta` and `ls_constants`, using fallback values if needed.
- Read `zmdg_os_repmap` for the target destination using `sap_destination_ecc`.
- Return a fatal response if the destination is not configured in `zmdg_os_repmap`.","Call `zcl_mdgc_online_store_util->create_v2` with the assembled customer data and destination.","Copy the returned customer number, message, and type back,`
Customer-specific configuration via replication mapping table `zmdg_os_repmap`
Maintains the RFC destination used by the inbound proxy when `sap_destination_ecc` is mapped to the backend destination.

zmdg_os_repmap | Mapping table used to find the backend destination for the target ECC system. |
zmdg_os_tvta | Provides organizational defaults such as company code, sales organization, distribution channel, sales office, sales group, and incoterms. |
zmdg_os_s_constants | Holds optional constant overrides used to default account, payment terms, payment history, sorting, and related customer values. |
