SAP MDG · REPLICATION INBOUND
How does the STA inbound replication method update KNVP data in SAP MDG?
The STA inbound replication method prepares current and old KNVP tables, handles delete mode by copying the record and blanking KZ in the old-image table, then calls remote function module ZMDG_UPDATE_STA_KNVP and returns the exported status.
The STA inbound replication method prepares current and old KNVP tables, handles delete mode by copying the record and blanking KZ in the old-image table, then calls remote function module ZMDG_UPDATE_STA_KNVP and returns the exported status.
The STA inbound `replicate_data` method follows a simple remote-update pattern: it prepares a current KNVP table, derives an old-image table only when the record is marked for deletion, and then calls the remote-enabled function module `ZMDG_UPDATE_STA_KNVP` in the target destination. The returned status is copied to `ev_status` so the caller can continue processing or react to the update result.
Process flow
- Initialize current and old KNVP tables.
- Check whether `is_knvp-kz = 'D'`.
- For delete records, append the current record to `lt_knvp` and a copy with blank `kz` to `lt_knvp_old`.
- For non-delete records, append only the current record to `lt_knvp`.
- Call `ZMDG_UPDATE_STA_KNVP` in RFC destination `iv_destination`.
- Import `ex_status` into a local status variable.
- Return the status in `ev_status`.
