Integration Monitoring and Error Handling

Keep this: job aid

Interface operations card

• Map every hop: document, S/4HANA interface layer, Cloud Connector, Integration Suite, partner acknowledgment.
• Know the monitors: WE02/BD87, SM58, SMQ1/SMQ2, SBGRFCMON, SRT_UTIL, /IWFND/ERROR_LOG, AIF, Integration Suite, Cloud ALM.
• Route errors to whoever can fix the cause; name owners per interface.
• Set severity by business impact and time to harm; tune out noise.
• Before reprocessing: cause fixed, result not already there, idempotency known.
• Reprocess originals where they failed; never delete without process-owner approval.
• Reconcile expected, sent and processed daily; control totals for money.
• Record message IDs, statuses and results as test evidence.
• Cutover: stop, drain or accept, reconnect, smoke test, monitor.
• Hypercare: daily review of alerts, failures, reconciliation and volumes against exit criteria.
