Oracle apps/ Oracle Reports Interview question
1. 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 schemas 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.
2. 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.
3. What is the
Significancy 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
FND_LANGUAGES -- COL --INSTALLED_FLAG I,B,D
I--INSTALLED,
B--BASE,
D--DISABLE
select
language_code,nls_language from fnd_languages where installed_flag like 'B'
4. Where did U find
the Applcation 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
5. Where can U find
the release version from backend?
SELECT release_name from FND_PRODUCT_GROUPS;
---11.5.10.2 .
6. What are the
Folders we will find below the 11.5.0 Folder?
Reports,forms,sql,lib,log,out,bin,admin,html,xml,msg,def,
etc
7. Can we create
Tables in the Apps Schema?
No.
8. 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.
9. 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 anyone can be execute in those program , which
programs are not imp yet this time we will
mention those programs in incompatibles tab.
10. 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
program by attach executable name in executable section. Then attach this CC
program to request group, Request group to Responsibility. Responsibility to
User.
11. What is meant by
Request group?
It is nothing but collection of cc programs.
12. What is Application Top? What are the types and Purpose?
A) 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.
13. What is US folder
in the Custom Top?
It is a
language specific folder used to store the G.U.I like reports and forms.
14. What are
mandatory parameters of Procedures and what the use of those?
Errorbuf: It is used
to returns the error messages and sent it to the log file.
Retcode: It is used
to show the status of the Procedure with 0, 1, and 2 0 for Completed Normal
1 for Completed Warning
2 for Completed Error
15 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.
16. What is Token?
a) Use to
transfer values to report builder and it is not case sensitive.
17. 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.
18.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
1002,”gvreddy”,2345,50
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 .

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.
21. FND USER EXITS:-
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
22. 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.
12) 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.
23. 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.
24. 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 responsibility
request.
h. Add and assign a concurrent program to a request group
25. FLEX FIELDS?
Used to capture the additional
business information.
DFF
KFF
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.
FLEX FILED : KEY : REGISTER
26. Difference
between Bind and Lexical parameters?
BIND VARIABLE:
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.
LEXICAL REFERENCE:
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.
27. 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 them.
28. 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.
29. What is Formula
Column?
A formula column
performs a user-defined computation on another column(s) data, including
placeholder columns.
30. 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.
31. What is TCA
(Trading Community Architecture)?
Ans. 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.
32. Difference

f. Cloning of OA
33. What are Flex
fields?
Ans. 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)
34. 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.
35. 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.
36. 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
37. Value Validation
Types?
1. Dependent
2. Independent
3. None
4. Pair
5. Special
6. Table
7. Translate Independent
8. Translate Dependent
38. 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.
Pl/Sql interview questions
1. What are the
various types of Exceptions?
User defined and
Predefined Exceptions.
2. Can we define
exceptions twice in same block?
No.
3. What is the
difference between a procedure and a function?

functions with the same name in a PL/SQL block?
Yes.
5. Can you have two
stored functions with the same name?
Yes.

stored function in the constraint of a table?
No.
7. What are the
various types of parameter modes in a procedure?
IN, OUT AND INOUT.

Overloading means an object performing different functions
depending upon the no. of parameters or the data type of the parameters passed
to it.
9. Can functions be
overloaded?
