The Top 10 Oracle Applications Developer Interview Questions and Answers

Landing a job as an Oracle Applications Developer requires strong technical skills and in-depth knowledge of Oracle products and tools. Preparing for the interview by reviewing common Oracle Apps Developer interview questions will help you highlight your abilities and stand out as a top candidate.

In this article we discuss the top 10 frequently asked Oracle Apps technical interview questions that assess your skills in areas like Oracle E-Business Suite SQL, PL/SQL, Forms, Reports, and OAF. Understanding these core topics is key to excelling in the interview and getting hired.

Set of Books

The set of books, often abbreviated as SOB, is a fundamental concept in Oracle General Ledger representing an accounting structure for a given organization.

Some key points about set of books:

• It is the highest level in the accounting hierarchy within Oracle GL

• It typically equates to a company code and allows multi- GAAP accounting.

• It controls the functional currency accounting calendar chart of accounts, and accounting rules.

• Multiple SOBs can be defined in Oracle GL to support different accounting representations.

During the interview, expect questions testing your understanding of how SOBs enable multi-GAAP compliance and flexible accounting setups in Oracle E-Business Suite.

Value Sets

Value sets are user-defined tables that store valid values for Oracle Application object attributes.

Key characteristics of value sets:

• They ensure data integrity by restricting users to predefined values only.

• Value sets are assigned to flexfields, profile options, function parameters etc.

• They can be dynamic (database values) or static (application defined).

• Value sets facilitate easier maintenance of lookup values.

• Examples of commonly used value sets: Yes/No, language, employee status etc.

Be ready to describe value sets, their purpose, and provide examples of where they are used in EBS.

Ad-hoc Reports

Ad-hoc reports refer to user-defined reports that can be quickly created in Oracle Apps without technical knowledge.

Key points about ad-hoc reports:

• They allow end users to extract data on-the-fly without IT help.

• Useful for analyzing scenarios and issues as they arise.

• Leverage existing SQL data definitions, no new coding required.

• Reporting tools like Oracle Discoverer, BI Publisher, OAF provide ad-hoc capabilities.

You can expect questions around developing or using ad-hoc reports to drive insights and productivity.

Calling WHO Columns in Forms

The WHO columns in Oracle Forms store auditing information like date/time of creation & modification, created/updated by user etc.

Techniques to call WHO columns in forms:

• Use PRE-QUERY trigger to fetch values and store in item variables.

• Place ENTER-QUERY trigger on item to reference variables.

• Use POST-QUERY trigger to populate item with values.

• Call FND_STANDARD API to retrieve WHO column values.

Be ready to summarize approaches for displaying WHO columns in forms.

Checking for Multi-Org Installation

Multi-org allows the use of multiple operating units within Oracle Apps. To check for multi-org:

• Navigate to System Profile Options form.

• Query for Profile Option MO: Operating Unit.

• If value is ‘Business Group’, multi-org is enabled.

• Also check Responsibility for ‘Multi Organization Access Control’.

• Descriptive flexfield Transaction Organization Code indicates multi-org.

Know how to verify multi-org installation as you may be asked during the interview.

Concurrent Manager Types

Oracle EBS uses concurrent managers to manage and execute concurrent programs. Common types include:

• Standard – manages high volume programs like reports.

• Parallel – enhances performance by running in parallel.

• Special Purpose – interface, workflow processes.

• CRON – Unix cron jobs.

• SLAVE – remote concurrent manager.

Understand the different concurrent manager types and their specific purposes.

Setting Operating Unit in Reports

To restrict a report to a specific OU in Oracle Apps:

• Navigate to Data Model of report object.

• Set organization security property to Operating Unit.

• Enter OU value in Parameter Form.

• OU can also be set in Runtime Parameter Form.

• Lexical parameter can be passed from calling form.

Be ready to discuss techniques for setting operating unit context in reports.
