ERP Integration Services: Fixing Event Order

Описание и применение

В статье описывается, как исправить проблемы согласованности в интеграции ERP, складской и CRM систем, используя паттерн outbox, явное моделирование бизнес‑событий и идемпотентные воркеры.

Задача

ERP integration services returned successful API responses while the business workflow remained incorrect, leading to inconsistent system states and manual reconciliation.

Результат

By separating business events from API calls, persisting events locally, and making workers idempotent, the integration achieves reliable ordering and consistency across ERP, warehouse, and CRM systems.

Рабочий процесс

• 1. Receive order and trigger business event sequence rather than inline API calls.
• 2. Persist order and corresponding business event in a local outbox table within a single transaction.
• 3. Dispatch events to external systems asynchronously via workers.
• 4. Ensure workers are idempotent by marking events processed and enforcing uniqueness in the database.
• 5. Use webhooks for notifications but keep workflow ownership in the worker logic.

Доказательства

The order reached the ERP. The warehouse received the inventory request. The CRM received the customer update. Every HTTP call returned 2xx.

The application then commits the order and event together:

ERP Integration Services should treat duplicate delivery as a normal condition.
