Sterling OMS OMS Interview Questions Integration Server Agent Server Transaction Pipeline UE Events Order Management

1. What is a Transaction in Sterling OMS?

A transaction defines a specific unit of work, like "Create Order" or "Schedule Order," which consists of one or more services executed sequentially as part of a pipeline.

2. What is a Pipeline in Sterling OMS?

A pipeline is a logical sequence of transactions that define how documents like orders or shipments are processed throughout their lifecycle.

3. How Do Pipelines Communicate with Each Other?

Pipelines interact using Listeners. A listener is configured to trigger downstream transactions or pipelines based on specific events or status changes.

4. What is a User Exit (UE)?

A User Exit is a predefined hook that allows you to inject custom Java logic into Sterling's processing flows without altering the core codebase.

5. What are Events in Sterling OMS?

Events are system signals that indicate changes (e.g., order created, shipped, or canceled). These can be used to trigger alerts, invoke services, or start agents.

6. What is the Difference Between Integration Server and Agent Server?

• Integration Server handles real-time service/API requests.
• Agent Server runs background jobs (e.g., time-triggered transactions).

7. What are Time-Triggered Transactions (TTTs)?

Also known as Agents, TTTs are background services scheduled to run periodically, used for tasks like auto-release of orders or processing alerts.

8. Explain the End-to-End Solution of Your Previous Project.

Example:

In my previous B2B project, I implemented a multi-node OMS where we handled order capture through web services, applied sourcing rules based on product zones, released orders to fulfillment centers, integrated with 3PL via XML, and handled returns using RMA flows with custom UIs.

9. What is a Customized API?

Customized APIs are either extensions of existing APIs or newly created services developed to fulfill business-specific scenarios that Sterling's base services don't handle.

10. How Do You Extend the Database in OMS?

Database Extension Steps:

Add new columns to existing tables or create custom tables → Update extn.xml → Regenerate entity classes → Use these extensions in custom logic or screens.
