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 appling 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 Application short name and base path
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 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 r 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
ccprogram by attach executable name in executable section. then attach
this ccprogram 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 .

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.
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 à Responsibility
à request.
h. Add and assign a concurrent program to a request group
25. FLEX FIELDS?
Used to capture the additional business information.
DFF:-
Additional
Captured in attribute prefixed columns
Not reported on standard reports
To provide expansion space on your form With the
help of [].
[] Represents
descriptive Flex field.
FLEX FILED :
DESCRIPTIVE : REGISTER
KFF:-
Unique Info, Mandatory
Segment prefixed
Is reported on standard reports
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 between Application Developer and System
Administrator?

a. Designing New Forms, Programs and Reports
b. Forms and Reports customization
c. Developing Interfaces
d. Developing PL/SQL stored procedures
e. Workflow automations
Role of System Administrator:
a. Define Logon Users
b. Define New/Custom Responsibility

f. Test Network Preferences
g. Define/Add new Modules
Role of an Apps DBA:
a. Installing of Application
b. up gradation
c. Migration
d. Patches
e. Routing maintenance of QA
f. Cloning of OA
33. What are Flex fields?
Ans.
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?
Ans.
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?
Ans.
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?
Ans.
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?
Ans.
1. Dependant
2. Independent
3. None
4. Pair
5. Special
6. Table
7. Translate Independent
8. Translate Dependent
38. Incompatibility in report registration and Run Alone?
Ans.
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.
39.What are the various types of Exceptions ?
User defined and
Predefined Exceptions.
40. Can we define exceptions twice in same block ?
No.
41.What is the difference between a procedure and a function
?
Functions return a single variable by value where as
procedures do not return any variable by
value. Rather they return
multiple variables by passing variables by reference through their OUT
parameter.
42. Can you have two functions with the same name in a
PL/SQL block ?
Yes.
43. Can you have two stored functions with the same name ?
Yes.
44. Can you call a stored function in the constraint of a
table ?
No.
45. What are the various types of parameter modes in a
procedure ?
IN, OUT AND INOUT.
46. What is Over Loading and what are its restrictions ?
OverLoading means an object performing different functions
depending upon the no. of parameters or the data type of the parameters passed to it.
47.Can functions be overloaded ?
Yes.
48. Can 2 functions have same name & input parameters
but differ only by return datatype
No.
49. Different types of NVL's
1) NVL
NVL (COMMISSION, 0)
2) NVL2
NVL2 ( string1, value_if_NOT_null, value_if_null)
returns second parameter if value_1 is not null
returns third parameter
if value_1 is null
Example
SELECT NVL2
(COMMISSION, 'Commission','No Commission')
This is equivelent to
DECODE
(COMMISSION, NULL, 'No Commission', 'Commission');
NVL2 first appeared in the 9i documentation,
but it appears in most (all ?) 8.x versions of Oracle as an
undocumented feature.
This function is not well understood, so it might be better
for you to use CASE instead to avoid confusion
3) LNNVL
LNNVL (condition)
returns TRUE if the condition is FALSE or NULL
return FALSE if the condition is TRUE
There is something fairly unique about LNNVL - it is one of
the few functions that can be used by SQL that use a BOOLEAN value or
condition.
Exists in 8i, 9i as an undocumented feature.
I would be careful using this feature as it appears to be
unstable in 10gr1 and 10gr2. Other
people have reported that the following query crashes the SQL session - try it
for yourself ... SELECT * FROM DUAL
WHERE NOT LNNVL(1=1)
LNNVL is similar to IS NOT TRUE and IS FALSE in the
SQL/Foundation 2003 SQL standard.
LNNVL is similar to NOT, except NOT converts NULL to NULL
LNNVL treats FALSE as NULL
This function can only be used in the WHERE section, not in
the SELECT <columns> section
LNNVL was first documented in 10gr2 at least. It works in earlier versions as an
undocumented and unsupported feature (I have tested and verified it works in
Oracle 8.1.7)
Oracle Database sometimes uses the LNNVL function internally
to rewrite NOT IN conditions as NOT EXISTS conditions
Example
SELECT *
from EMP
where LNNVL(SAL > 1000)
This is the same as ...
SELECT *
from EMP
where NOT (SAL > 1000)
Truth Table
NOT LNNVL
===== =====
TRUE FALSE FALSE
FALSE TRUE TRUE
NULL NULL TRUE
This function is not
well understood, so it might be better to CASE or NOT to avoid confusion
4) NULLIF
NULLIF (A, B)
return NULL if A = B, else return A
SELECT NULLIF ('A', 'A'),
-- returns NULL
NULLIF ('A',
''), -- returns A
NULLIF ('',
'A'), -- returns NULL
NULLIF ('A',
NULL), -- returns A
NULLIF ('',
'') -- returns NULL
from DUAL
5) COALESCE
COALESCE (my_variable, last_name, salary, <n>)
returns the first not null value in the list
SELECT COALESCE (null,null,30,null,40) -- this returns 30
FROM DUAL
SELECT COALESCE (SALARY, BONUS, COMM)
FROM EMP
6) DECODE
One for the old school fans.
DECODE has gradually fallen out of use and CASE now tends to be used
instead of DECODE.
SELECT decode (daily_rate
,null
,'No Value'
,1 ,'Low'
,2 ,'High'
,daily_rate
)
SELECT ename,
comm,
DECODE (comm,
NULL,
'No Commission',
'Commission'
),
from emp
CASE does not match NULL
DECODE does matches NULL - old school works better !
7) CASE
SELECT ename,
job,
CASE job
WHEN
'PRESIDENT' THEN 'Grand Pooh Bah'
WHEN
'CLERK' THEN 'Worker Bee
ELSE 'Other
Jobs'
END
from emp
SELECT last_name,
CASE status
WHEN 'A' THEN
'Active'
WHEN 'I' THEN
'Inactive'
ELSE 'Unknown'
END
from employees
There is a minor difference between CASE and DECODE
CASE does not
match NULL
DECODE matches NULL
