Oracle Apps Technical Interview Questions

What is Oracle Apps (ERP)?

ERP stands for Enterprise Resource Planning. A product of Oracle India Pvt. Ltd. As the name suggests Enterprise Resource Planning. Enterprise means a firm/organization. Resource means available source of wealth in firm and Planning means how you can maintain day to day resource. Hence in short to facilitate big businesses, companies Oracle Corporation have created huge software known in the category of ERP (Enterprise Resource Planning) as Oracle Applications.What is the Diff between APPS Schema and other Schemas?

Apps schema contains only Synonyms we can’t create tables in apps schema,where as other schema s contains tables, & all the objects. Here only we will create the tables and giving grants on created tables. Almost all every time we  will connect to apps schema only.

What are cycles of GL, AP, and AR?

In general, GL AP and AR consist of:

Structure PhaseDefines the process flows and configuration for the system and Conduct business process and data mapping workshops.

Construct Phase – Contains all of the configuration activities

Transition Phase – Executes system test

Deploy Phase – Migrates database to customer environment

What is FlexField? Explain types of flexfields?

We can assume FlexField as a collection of segments or sub-fields which can be added or removed to modify the structure of the FlexField and does not require any levels of programming. It is just a pop-up window which has a cause for each segment.

There are two types:

Key FlexFields  is used for creating unique identifiers or constraints. It is the building block which defines the structure of objects. Key flexfields are flexible enough to let any organization use the code scheme they want, without programming. With the help of Key Fields an organization can define rules to specify which segment values can be combined to make a valid complete code (also called a combination).

-Descriptive FlexField is used to create new fields on screen and capture other information. Also provides customizable”expansion space” on your forms. Descriptive flexfields can be context sensitive, where the information your application stores depends on other values your users enter in other parts of the form.

What are the businesses needs satisfy by the Oracle Applications flexfields?

The following businesses needs are served by FlexField:

– You can query the key fields.
– Helps in customization of data fields without programming.
– Helps in validating the values.
– Customize your applications to capture data that is not been tracked by your application.
– Consist of intelligent fields which comprised of one or more segments, where each segment has both a value and a meaning.

What is meant by Custom Top and what is the Purpose?

Custom Top is nothing but Customer Top, which is created for customer only. we can have multiple custom tops based on client requirement. It is used to store developed & customized components. whenever oracle corp applying patches it will over ride on all the modules except custom top. that’s why we will use custom top.

What is the Significance of US Folder?

It is nothing but language specification by default it is in american language. We can have multiple languages folders  based on installed languages. from backend we can get it from





select language_code,nls_language from fnd_languages where installed_flag like ‘B’

What are different types of invoices and what is a recurring invoice?

Types of Invoice: Standard Invoice, Credit Memo Invoice, Debit Memo Invoice, Expense Invoice, Recurring Invoice With-hold tax Quick Match and Pre-Payment Invoice.

Recurring Invoice: As the name suggests the invoice that occurs at regular interval of time is known as the Recurring Invoice.

What is FSG? Explain its uses.

FSG stands for financial statement generator. It is powerful reporting engine for clearly define our reporting requirement. Helps in keeping the reporting simple by the use of Row Set, Reports, Content set and Column set. It uses ADI request set to publish standard reports.


– Can produce a specific report when needed.
– Produce financial report without programming.
– Asynchronous printing of reports.
– Ability to print single reports for multiple firms.

What is MRC? Explain its uses?

MRC stands for Multiple Reporting Currencies. It has default currency as US $. And if any organization books with some other currency there comes the requirement of MRC. Hence through MRC we can use currency as per our wish.

– Transaction-Level Conversion.
– Inquiry and Reporting in Multiple Currencies.
– Euro Support. MRC allows Oracle Applications to support organizations that are transitioning from their national currency to the Euro.

Where did U find the Application short name and basepath names?

select basepath,application_short_name from fnd_application from the backend. From the from end we can get it Navigation Application Developer.—–> Application—->Register The application name we will get from FND_APPLICATION_TL

 Can we create Tables in the Apps Schema?


 Can we have custom schema when it it required?

yes, we can have custom schema, when we want to create a new table we required custom schema.

 What is meant by concurrent Program?

It is nothing but Instance of the execution along with parameters & Incompatibles. Here Incompatibles nothing but if we  are submitting cc programs if any one can be execute in those program , which programs r not imp yet this time we will  mention those programs in incompatibles tab.

What are the steps we will follow to register Reports as Concurrent Program?

First develop the report & save it in local machine. upload into custom_top/11.5.0/reports/us/ go to system  administrator  open executable form create executable by mentioning executable method as reports ,executable  as report name which  was created. go to cc program form create ccprogram by attach executable name in executable section. then attach this  ccprogram to request group, Request group to Responsibility.Responsibility to User.

 What is meant by Request group?

It is nothing but collection of cc programs.

 What is Application Top? What are the types and Purpose?

When we connect to the server we will find the top called application top. Under application top we have

Product top.

Custom top

Product top is the default top built by the manufacturer. Custom top is used to select the Client for his business purposes. Customizations are done with the Custom top.

 What is US folder in the Custom Top?

 What is Apps Schema and Schema?

Schema: Schema is the location in database contains database objects like views, tables, and synonyms.

Apps Schema: It is used to connect the all schemas to get the information from The database.

 What is Token?

a) Use to transfer values to report builder and it is not case sensitive.

Difference between FORM, Function and Menu?

a) A menu is a hierarchical arrangement of functions and menus. Each responsibility has a menu assigned to it. A function is a part of an application that is registered under a unique name for the purpose of assigning it to be including it from a menu.

Explain how to handle errors in Customer interface.

We can handle errors by using SQL*Loader, or other import program, to load customer information into the interface tables.

When you import customer information, the Customer Interface program validates the global attribute columns in the interface tables and transfers those values into the customer tables.

Get through the interview bar with our selected interview questions for Oracle Apps Technical enthusiasts

Tell me something about SQL-LOADER.

Sql * loader is a bulk loader utility used for moving data from external files into the oracle database.

Sql* loader supports various load formats, selective loading, and multi-tables loads.

1) Conventional –The conventional path loader essentially loads the data by using standard ‘insert’ statement.

2) Direct — The direct path loader (direct = true) by possess of logic involved with that, and loads directly in to the oracle data files.

EX:- My data.csv file

1001, “scott tiger”,1000,40


Load data

Infile ‘c:\data\mydata.csv’

insert Into table emp Fields terminated by “,” optionally enclosed by‘”’

(empno, empname,sal,deptno)

>sqlldr scott/tiger@vis control=loader.ctl log= gvlog.log bad=gvbad.bad discard=gvdis.dsc .


Collection of Chart of Accounts and Currency and Calendars is called SOB

What is the use of CUSTOM Library in Oracle Apps?

– The main beneficial use of the custom library is allowing extension to Oracle Application without modification of Oracle Application code.

– We can do the customization such as Zoom, enforcing business rules and disabling fields that do not apply for your site.

– Also used to validate the base application without modifying the Custom.pll.

– The CUSTOM library is an Oracle Forms PL/SQL library.

– It allows you to take full advantage of all the capabilities of the Developer/2000 suite of products, and integrate your code directly with Oracle Applications without making changes to Oracle Applications code.

– The CUSTOM library is located in the $AU_TOP/res/plsql directory (or platform equivalent).

– The CUSTOM library you modify must replace the default CUSTOM library in this directory in order for your code to take effect.

– After you write code in the CUSTOM procedures, compile and generate the library using Oracle Forms.

– Then place this library into $AU_TOP/res/plsql directory (or platform equivalent).

– Subsequent invocations of Oracle Applications will then run this new code.

– The specification of the CUSTOM package in the CUSTOM library cannot be changed in any way.

– You may add your own packages to the CUSTOM library, but any packages you add to this library must be sequenced after the CUSTOM package.

– To ensure that your packages remain sequenced after the CUSTOM package even after a conversion from a .pld file, when program units are alphabetized.

Tell me what r the Base tables in the AR?
hz_parties (party_id) (store info about org, groups and people)

HZ_PARTIES stores information about parties such as organizations,

people, and groups, including the identifying address information for the party.

hz_cust_accounts (cust_account_id)

HZ_CUST_ACCOUNTS stores information about customer relationships. If a

party becomes a customer, information about the customer account is stored in this table. You can establish multiplecustomer relationships with a single party, so each party can have multiple customer account records in this table.

hz_cust_acct_sites_all (cust_acct_site_id)

HZ_CUST_ACCT_SITES_ALL stores information about customer sites. One

customer account can have multiple sites. The address is maintained in HZ_LOCATIONS.

hz_cust_site_uses_all (site_use_id)

HZ_CUST_SITE_USES_ALL stores information about site uses or business

purposes. A single customer site can have multiple site uses, such as bill to or ship to, and each site use is stored as a record in this table.

hz_party_sites (party_site_id)

HZ_PARTY_SITES stores information about the relationship between Parties

and Locations. The same party can have multiple party sites. Physical addresses are stored in HZ_LOCATIONS.

hz_locations (location_id)

HZ_LOCATIONS stores information about physical locations.

hz_Person_Profiles (person_profile_id)

HZ_PERSON_PROFILES stores detail information about people.

hz_Organization_Profiles (organization_profile_id)

HZ_ORGANIZATION_PROFILES stores credit rating, financial statistics,

socioeconomic and corporate linkage information for business sites. The primary key for this table is ORGANIZATION_PROFILE_ID.


FND SRWINIT sets your profile option values, multiple organizations and allows

Oracle Application Object Library user exits to detect that they have been called by an Oracle Reports program.

FND SRWEXIT ensures that all the memory allocated for AOL user exits have been freed up properly.

FND FLEXIDVAL are used to display flex field information like prompt, value etc

FND FLEXSQL these user exits allow you to use flex fields in your reports

FND FORMAT_CURRENCY is used to print currency in various formats by using formula column

 What is Value Set?

The value set is a collection (or) container of values.

Whenever the value set associated with any report parameters. It provides list of values to the end user to accept one of the values as report parameter value.

If the list of values needed to be dynamic and ever changing and define a table

based values set.

What are the validation types?

1) None ——– validation is minimal.

2) Independent ——input must exist on previously defined list of values

3) Dependent ——input is checked against a subset of values based on a

Prior value.

3) Table —– input is checked against values in an application table

4) Special ——values set uses a flex field itself.

5) Pair —— two flex fields together specify a range of valid values.

6) Translatable independent —– input must exist on previously defined list

of values; translated values can be used.

7) Translatable dependent ——- input is checked against a subset of values

based on a prior values; translated value can be used.

Form development process?

a) Open template form

b) Save as <your form>.fmb

c) Change the form module name as form name.

d) Delete the default blocks, window, and canvas

e) Create a window.

f) Assign the window property class to window

g) Create a canvas (subclass info)

h) Assign canvas property class to the canvas

I) assign the window to the canvas and canvas to the window

j) Create a data block

k) Modify the form level properties. (sub class item Text item)

l) Modify the app_custom package. In the program unit.

m) Modify the pre-form trigger (form level)

n) Modify the module level properties ((console window, First navigation

p) Save and compile the form.

Place the .fmx in the server directory.

 How does u customize the Reports?

a. Identify the Short name of the standard report in which module we have to customize

Ex: – if u wants to customize in the AR module path is

Appl top\ar\11.5.0\reports\US\ .rdf

b. Open the .rdf file in Report builder and change the name of the module.

c. Open the data module and modify the query (what is client requirements) assign the columns to the attributes.

d. Go to report wizard and select, what r the newly created columns.

e. Then Compile it. Then u will get a .rep file in the specified module. If it is not in the specified directory then we have to put in the server directory.

f. Then Register in the AOL Concurrent Executable and Concurrent Program.

g. Go to system administrator Security àResponsibility àrequest.

h. Add and assign a concurrent program to a request group


Used to capture the additional business information.



Additional    Unique Info, Mandatory

Captured in attribute prefixed columns    Segment prefixed

Not reported on standard reports    Is reported on standard reports

To provide expansion space on your form With  the  help of [].

[] Represents descriptive Flex field.

FLEX FILED : DESCRIPTIVE : REGISTER    Used for entering and displaying key information

For example Oracle General uses a key Flex field called Accounting Flex field to uniquely identify a general account.


 Difference between Bind and Lexical parameters?


are used to replace a single value in sql, pl/sql

bind variable may be used to replace expressions in select, where, group, order

by, having, connect by, start with cause of queries.

bind reference may not be referenced in FROM clause (or) in place of

reserved words or clauses.


You can use lexical reference to replace the clauses appearing AFTER select,

from, group by, having, connect by, start with.

You can’t make lexical reference in pl/sql statements.

What is Flex mode and Confine mode?

Confine mode:

On: child objects cannot be moved outside their enclosing parent objects.

Off: child objects can be moved outside their enclosing parent objects.

Flex mode:

On: parent borders “stretch” when child objects are moved against them.

Off: parent borders remain fixed when child objects are moved against


 What is Place holder Columns?

A placeholder is a column is an empty container at design time. The placeholder can hold a value at run time has been calculated and placed in to It by pl/sql code from anther object.

You can set the value of a placeholder column is in a Before Report trigger.

Store a Temporary value for future reference. EX. Store the current max salary as records are retrieved.

 What is Formula Column?

A formula column performs a user-defined computation on another column(s) data, including placeholder columns.

What is Summary columns?

A summary column performs a computation on another column’s data. Using the Report Wizard or Data Wizard, you can create the following summaries: sum, average, count, minimum, maximum, % total. You can also create a summary column manually in the Data Model view, and use the Property Palette to create the following additional
summaries: first, last, standard deviation, variance.

 What is TCA (Trading Community Architecture)?

Oracle Trading Community Architecture (TCA) is a data model that allows you to manage complex information about the parties, or customers, who belong to your commercial community, including organizations, locations, and the network of hierarchical relationships among them. This information is maintained in the TCA Registry, which is the single source of trading community information for Oracle E-Business Suite applications.

 What are Flex fields?

A Flex field is a customizable field that opens in a window from a regular Oracle Applications window. Defining flex fields enables you to tailor Oracle Applications to your own business needs. By using flex fields, you can:

(a) Structure certain identifiers required by oracle applications according to your own business environment.

(b) Collect and display additional information for your business as needed.

Key Flex fields: You use key flex fields to define your own structure for many of the identifiers required by Oracle Applications. Profile – ‘Flexfields:Open Key Window’ (FND_ID_FLEXS)

Descriptive Flex field: You use descriptive flex fields to gather additional information about your business entities beyond the information required by Oracle Applications. Profile – Flex fields: Open Descr Window’ (FND_DESCRIPTIVE_FLEXS)

 Report registration process?

1. Create the report using the report builder.

2. Place the report definition file in the module specific reports directory.

3. Create an executable for the report definition file.

4. Create a concurrent program to that executable.

5. Associate the concurrent program to a request group.

 Define Request Group?

A request security group is the collection of requests, request sets, and concurrent programs that a user, operating under a given responsibility, can select from the Submit Requests window.

 Value Sets?

Oracle Application Object Library uses values, value sets and validation tables as important components of key flex fields, descriptive flex fields, Flex Builder, and Standard Request Submission.

When you first define your flex fields, you choose how many segments you want to use and what order you want them to appear. You also choose how you want to validate each of your segments. The decisions you make affect how you define your value sets and your values.

You define your value sets first, either before or while you define your flex field

segment structures. You typically define your individual values only after your flex field has been completely defined (and frozen and compiled). Depending on what type of value set you use, you may not need to predefine individual values at all before you can use your flex field.

You can share value sets among segments in different flex fields, segments in

different structures of the same flex field, and even segments within the same flex field structure. You can share value sets across key and descriptive flex fields. You can also use value sets for report parameters for your reports that use the Standard Report Submission feature.

Navigation Path:

Login – Application Developer -> Application -> Validation -> Set

 Value Validation Types?







-Translate Independent

-Translate Dependent

 Incompatibility in report registration and Run Alone?

Identify programs that should not run simultaneously with your concurrent program because they might interfere with its execution.

You can specify your program as being incompatible with itself.

Application: Although the default for this field is the application of your concurrent program, you can enter any valid application name.

Name: The program name and application you specify must uniquely identify a concurrent program. Your list displays the user-friendly name of the program, the short name, and the description of the program.

Scope: Enter Set or Program Only to specify whether your concurrent program is zincompatible with this program and all its child requests (Set) or only with this program (Program Only).

Run Alone: Indicate whether your program should run alone relative to all other programs in the same logical database. If the execution of your program interferes with the execution of all other programs in the same logical database (in other words, if your program is incompatible with all programs in its logical database, including itself), it should run alone.
