Getting a job in Oracle E-Business Suite requires more than just theory — hiring managers expect knowledge you can prove. This Oracle EBS interview questions guide contains the most frequently asked questions to help you through your interview process.
What is Oracle EBS?
Oracle E-Business Suite (EBS) is a suite of integrated applications for automating business processes like ERP, CRM, and SCM offered by Oracle. It handles Finance, HR, supply chain, and manufacturing as well, all under one system.
Oracle EBS Interview Questions and Answers for Freshers
These Oracle EBS Interview Questions are very important and are asked in interviews of Oracle EBS freshers.
Here's what to expect:
Q1. What are the major modules of Oracle EBS?
A. Oracle EBS includes many key modules, such as Oracle Financials, Oracle HRMS, Inventory, and Purchasing. Although each module focuses on a particular business area, they all share the same database and support one another.
Tip: Don’t include modules that have the same underlying data model. This will let them know you understand integration, not just the usability of the individual modules.
Q2. What is Flexfield in Oracle EBS?
A. A Flexfield is a customizable field in which you can hold additional business data without writing code.
They are of two types:
- Key Flexfields — like Account or Item, define codes
- Extensibility Flexfield — adds more data at the form level in a different manner that is somewhat constrained by the object being extensible.
Each can be completely customized with no coding required.
Q3. What is the difference between a responsibility and a user?
A. A user is a person who logs in to the Oracle EBS. Responsibility represents the picks from the menu, and the user's access right to run the functions as well as query the data. One user can have multiple responsibilities.
Remember This: Frame it with a real-world analogy — “A user is like an employee, and a responsibility is like their job role with specific access rights.”
Q4. What is Multi-Org in Oracle EBS?
A. Multi-Org enables you to run multiple legal entities and business units within a single Oracle EBS instance and still keep the data isolated.
Q5. What is a concurrent program in Oracle?
A. A concurrent program is a background process for doing batch jobs, reporting, or any large data processing. Through the Concurrent Manager, users schedule and monitor these.
Oracle EBS Technical Interview Questions
Oracle EBS technical interview questions test your expertise in development tools, database structures, and customized frameworks. Strong technical answers here can distinguish you as a candidate.
Q6. What is RICE in Oracle EBS?
A. RICE is an acronym for standard components used to handle technical customizations in Oracle EBS implementation ( Reports, Interfaces, Conversions, and Extensions).
Remember This: Expand the acronym clearly in your answer, and then one quick example for each site would be good. It reveals depth, not just rote memorization.
Q7. What is the use of Oracle EBS APIs?
A. They are a series of pre-written PL/SQL procedures and functions in EBS, which we can utilize to safely insert or update data without inserting directly into base tables.
Major applications:
- Upload the data in the AP, AR, and GL modules
- Apply the built-in validations of business rules
- Avoid data integrity problems by direct DML on system tables.
Q8. What does AD Utilities mean in Oracle EBS?
A. AD Utilities are used to manage and maintain Oracle EBS installations. AutoPatch runs patching, AD Admin replaces, so to speak, and AutoConfig writes out your configuration files.
Q9: What are the tools involved in EBS development?
A. EBS application developers generally use Oracle Forms, Oracle Reports, PL/SQL, SQL Plus, and Oracle Workflow and BI Publisher to develop and customize the EBS applications.
Q10. What is the difference between a View and a Synonym?
A. View is a virtual table constructed from an SQL query. A Synonym is an alias for a database object, but in EBS, it is used to refer to an object across schemas consistently.
Oracle EBS Functional Interview Questions
The Oracle EBS Functional Interview Questions assess your knowledge of how the business should run, as well as the module configurations. These are must-know questions for functional Consultant/Business Analyst aspirants.
Q11. What is the Procure-to-Pay (P2P) cycle?
A. P2P is a procedure that starts with the writing of the purchase requisition and ends with the vendor payment. It tightly integrates with Oracle Purchasing and Oracle Payables as well as Oracle Cash Management.
Q12. What is the Order To Cash (O2C) cycle?
A. The order to cash starts with the customer order and ends when the payment is collected. It consists of Order Management, Shipping, Accounts Receivable, and Cash Management modules.
Say This in Your Interview: “O2C is really the revenue cycle — I always think of it as the path from ‘customer says yes’ to ‘cash in the bank.’” It’s a phrase that helps you put it into context.
Q13. What is AutoAccounting in Oracle Receivables?
A. AutoAccounting is a feature of Oracle Receivables that automatically generates GL account code entries for AR transactions such as invoices and credit memos based on rules defined by transaction type, salesperson, or item.
Common Mistake to Avoid: Don’t say that AutoAccounting “creates” journal entries — what it creates are account numbers. Actual journal entries are generated when transactions are posted to GL.
Q14. What is the difference between a Standard and Blanket PO?
A. A Standard PO is a single purchase order without a supplier agreement. A Blanket PO is a long-term agreement with a vendor to purchase a specific quantity of items or services from that vendor.
Q15. What is a Payment Term in Oracle Payables?
A. Payment Term defines when a supplier invoice is payable. It may specify early payment discounts and rules for when a payment is due, and it can be assigned to either the invoice or the supplier.
Pro Tip: Add “Net 30” or “2/10 Net 30” to show you understand both the Oracle system and the accounting rationale behind it."
Oracle EBS Financials & SCM Interview Questions
A good knowledge of Financials & SCM is a must if one is looking for a role in the finance sector. These questions often come in functional and technical rounds.
Q16. What is a Journal Entry in Oracle GL?
A. A Journal Entry is the log of financial information, debits , and credits, for transactions in Oracle General Ledger. Entries can be entered manually, imported from subledgers, or auto-generated using templates for recurring transactions.
Q17: How does Physical Count differ from Cycle Count inventory?
A. Physical Count is when everything is counted at one time, typically during a shutdown. Cycle Count is a process of continual rotation counting.
Major differences:
- Physical count requires the shutdown of the entire system
- Cycle counting is ideal for busy, high-turnover warehouses.
Q18. What is Oracle Subledger EBS?
A. Sub-ledgers, such as AP, AR, Fixed Assets, and Inventory, post accounting entries to the General Ledger. They contain transactional details, while GL contains an aggregated view for financial reporting.
Q19. What is Oracle Cash Management for?
A. It matches Oracle AP and AR transactions to bank statements and is an important tool for bank reconciliation. Cash Management helps organizations manage liquidity, perform bank reconciliation, and accurately forecast cash positions.
Insider Tip: Highlight that Cash Management is the link between bank and Oracle bank – rarely mentioned by candidates yet frequently asked in Financials-centric interviews.
Q20. What is a Receiving Transaction in Oracle Purchasing?
A. A receiving transaction logs the goods received against your purchase order (PO). This initiates the three-way matching process (PO, receipt, invoice) and reduces inventory quantities on hand.
Some Scenario-Based & Real-Time Interview Questions
Scenario-type questions are where most candidates have a hard time they tell if you can really use what you know. When you're dealing with Oracle EBS Developer Interview Questions or DBA-style questions, think out loud and demonstrate how you think through problems. For additional guidance, practicing through
oracle courses online can help you gain practical experience and confidence.
Q1. A duplicate payment has been processed for one invoice. What to do?
A. Confirm the duplicate invoice in Oracle Payables, then work with the vendor for a refund or credit.
System procedure:
- Stop payment if the check has not been cashed.
- Cancel the duplicate payment in the system.
- Balance the adjusted amount in Cash Management.
Q22. An invoice is stuck in approval. What should I do?
A. Search the Oracle Workflow Monitor for the workflow status. Typical reasons are an inactive approver or an invalid AME rule. Fix the approver and resubmit the workflow.
Q23. Following a receiving transaction, the quantities of inventory are not updated. What’s your approach?
A. Verify that the transaction is completed and that the inventory interface has executed well.
Next steps:
- Check MTL_TRANSACTIONS_INTERFACE for errors
- Re-run the Transaction Manager
- Check the UOM and organisation for inconsistencies
Very Common Mistake: Don't automatically assume it is a technical problem – it is sometimes a setup or configuration problem.
Q24. The General Ledger accounting periods are closed, and a subledger transaction needs to be posted. How can I fix this?
A. Open an adjustment period in Oracle GL( if policy allows), post the transaction, and close it after that. Alternatively, in the current open period, reverse and reenter the transaction.
Q25. Payment received from the customer, but not applied to the invoice. What would you do?
A. Enter Oracle AR (Receipts workbench). Manually apply the unapplied receipt to the invoice. If AutoApply is selected, verify the match rules and the remittance info.
