A Segment Qualifier identifies a particular type of value in a single segment of a key flex field.
1. What is a Dynamic Insertion?

Dynamic Insertion is the insertion of new valid combination into a Key Flexfields Combinations Table from a form other than the combinations form.
All Validation rules still will apply during insertion.
1. What are the different Level of Profiles?

User Profiles are used
To set options that affect your applications behavior o your preference.
A Collection of changeable options that affect the way your applications run
Modify Product Specific variables
Gives Control over certain Oracle Applications features.

Profile Levels
Site Level
Application Level
Responsibility Level
User Level
Note: Site Level is the lowest level.

1. Explain Multi-Organization Structure?

Set of book
A financial reporting entity that uses a particular chart of accounts, functional currency and accounting calendar.
Business Group This is highest level in the Organization Structure. The Business group secures HR Information. Multiple set of books can share same business 

group. Legal Entity A legal company for which you prepare fiscal or tax reports. Balancing Entity
Represents an accounting entity for which you prepare financial statements.
This is the segment in Accounting Flexfield.
Operating Unit
An Organization that Uses Oracle Cash Management, Order Management and shipping Execution, Oracle Payables, Oracle Purchasing, Oracle receivables.
It may be a Sales office division or a department. An Operating Unit is associated with legal entity.
Inventory Organization An Organization for which you track Inventory transactions and balances and/or an Organization that manufactures or distributes products. HR Organization
HR Organization represents the basic work structure of any enterprise. They usually represent Functional Management or reporting groups that exists within a business group.
1. How can u see Multi-Organization is enabled or not from SQL Prompt? 
SELECT MULTI_ORG_FLAG FROM fnd_product_groups;

1. What are the two mandatory parameters required for PL/SQL stored Procedure Concurrent Program? Errbuf and retcode two OUT Parameters are required while defining PL/SQL stored Procedure Concurrent Program.
Errbuf Returns any error messageand retcode returns completion status.
Retcode returns 0 for success, 1 for warnings and 2 for error.

1. Different Type of Value Sets. What is exactly Translatable independent and Translatable Dependent Value Sets (Introduced in latest version of 11i). Ans:- There are 8 types of Values Sets.
i. None (Non Validate at all) (Validation is Minimal)
j. Independent (Input must exist on previous defined list of values)
k. Dependent (Input is checked against a subset of values based on prior Value) 
60 l. Table (Input is checked against a subset of values in an application table)
m. Special (advanced) (Value set uses a flexfield itself)
n. Pair (advanced) (Two Flexfields together specify a range of valid values)
o. Translatable Independent (Input must exist on previous defined list of values. Translated value can be used)
p. Translatable Dependent. (Input is checked against a subset of values based on a prior value; translated value can be used)
(Note:- When you first define your flexfields, 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.)

1. How to run a concurrent program. What all concurrent programs u have created. Ans:- (Definition :- A concurrent program is an instance of an execution filealong with parameter definitions and incompatibilities. Concurrent programs use concurrent program executables to locate the correct execution file.)
Oracle Tool Concurrent Program * A concurrent program written in
Oracle Reports, PL/SQL package procedures,
SQL*Loader, SQL*Plus, Host Scripting.
How to Run : * Write a execution file and place in correct directory.
Establish executables in Oracle apps specify execution file and method.
Define Concurrent Program (Program, Parameters and Incompatibilities)
Call your Program (- Thu application form, from other concurrent program.
- OR through standard request submission, you must check the „USE in SRS check box‟ and register your program parameters when you define your concurrent program. Add your program into the request security group for your custom application.)
I have created reports through concurrent program, load(sql*loader/pl-sql pkg-proc) the file through concurrent program.


224) What is parameter in apps and from where u can create it. Ans:- Parameters only using in report, you can create in defining the report in
apps (you can create the parameter there only). 
225)What all are the tables used in the modules u have worked on. *In GL – I have worked on GL_JE_HEADERS(JOURNALS HEADER),GL_JE_LINES(JOURNAL LINES), GL_JE_BACHES(JOURNAL BATCHES), GL_SET_OF_BOOK(SET_OF_BOOK_ID),
*In PO- I have worked on PO_HEADER_ALL….. 
226)What is Profile? Explain different levels of Profile. Ans:- A user profile is a set of changeable options that affects the way your
applications run. Oracle Application Object Library establishes a value
for each option in a user‟s profile when the user logs on or changes
responsibility. Your user can change the value of profile options at any
time a) To create Profile Option. ( 
Profile Option can created by developer in application developer area) b)set the value (Values of the profile option , who will have what value at various levels is set by SYSADMIN). Oracle Application Object Library provides many options that. (Edit profile feature for every user is available to set any value to allow the user).your users can set to alter the user interface of your applications to satisfy their individual preferences. Profile Option – set at run time like – User Related, responsibility, Sequence, Printer, Security.


61 Values in 4 Levels(HIEARCHY WISE) :- E. USER
F. RESPONSIBILITY
G. APPLICATION
H. SITE
Application Developer 
create the profile. System Administrator make profile option. (NOTE:- If any change in value, it will active when you re-login or switch to the responsibility.)
( Usage in the multi-tier, the profile is biggest impact)


227)How to restrict the data for a responsibility as per the ORG-ID Ans:-Through Multi – Org(MO) u can restrict the data for a responsibility as per the ORG-ID. Only in GL- Set of book Id you set the value to restrict the data for a responsibility. 228) is Flexfield? What is flexfield qualifier and what is segment qualifier? Ans:- A flexfield is made up a segments (Which are actually table columns). Each segment has a name that can be assigned, and set of valid value.
Purpose and Application:-
* Flexibility to implement code structure.
* Flexibility to capture additional information.
Two Types of Flexfields in oracle apps.
1. Key Flexfields (KFF)
2. Descriptive Flexfields (DFF)
A key flexfield segment has a name you assign, and set of valid values you specify. Each value has a meaning which can be specified. 
Flexfield Qualifier:-flexfield qualifieridentifies a particular segment of a key flexfield.. Usually an application needs some method of identifying a particular
segment for some application purpose such as security or computations. However, since a key flexfield can be customized so that segments appear in any order with any prompts, the application needs a mechanism other than the segment name or segment order to
use for segment identification.
Segment Qualifier :- A segment qualifier identifies a particular type of value in a single segment of a key flexfield.
In the Oracle Applications, only the. Accounting Flexfield uses segment qualifiers. You can think of a segment qualifier as an "identification tag" for a value. In the Accounting Flexfield, segment qualifiers can identify the account type



229)Which flexfield qualifiers are mandatory? Ans:- „Balancing Segment‟ flex field qualifier is mandatory. 230)Difference Between versions of Apps.(Front end & Database) Ans:- In backend- Client server architecture (old)/ Three tire architecture
In font end- Client Server Application (old)/ Web Based application 



231)What is MULTI-ORG and what is structure of multi-org. Ans:- Use a single installation of any oracle applications product to support any number of organizations. if those organizations use different set of books.
Support any number or legal entities with a single installation of oracle applications. 
62 Secure access to data so that users can access only the information that is relevant to them. Structure :- Business Unit -HRMS(Employee)
-GL(Set of Books)(Currency, Calendar, Chart of Account)
|
Balancing Segment(You can do multiple balancing segment)
-Operating Units (Purchase, Selling, Fixed Asset, Payable,
Receivables)
-Inventory Organizations (Storing Items, Transaction Happening,
Ware Housing)
(Note:- Means if you maintaining GL(set of book id), If u have operating unit, if you
have inventory then its called MULTI-ORG)


232)What is difference between ORG_ID and ORGANIZATION_ID in Multi-Org.
At where we can set ORG_ID and ORGANIZATION_ID level it comes in the
structure. 
Ans:-A Global Variable exists in the oracle database called CLIENT_INFO, which is 64 bytes long. The first 10 bytes are used to store the operating unit ID(or ORG_ID) for the multiple organization support feature.
Multi-Org views are partitioned by ORG_ID. The ORG_ID value is stored in CLIENT_INFO variable.(It comes in AP,PO,AR,OM level)
ORGANIZATION_ID – Its for Inventory, Mfg, & BOM.
15.Q.What are the default types of parameters. What is the use of each one of it.
Ans:-****** 


233)ORG_ID can be set at master levels or transaction level. Ans:- ORG_ID can be set at transaction Level. 234)Differnet type of execution methods in Conc.Progs. Explain Each Type. Ans:- a.Oracle Reports- You can register your report as executable file type is oracle reports.
b. PL/SQL Package Procedure - You can register your PL/SQL Package Procedure as executable file type is oracle PL/SQL Package Procedure.
1. SQL Loader- You can register your SQL Loader SQL Loader is your executable file type.(for data loading)
2. SQL*Plus :- You can register your SQL script as SQL*Plus executable type.
3. Host Scripting:- You can write down Unix Host scripting and register here. 


235)What is difference between oracle schema and apps schema. Ans:-Database Schema-
The APPS schema- is an ORACLE schema that has access to the
complete Oracle Applications data model. This schema is maintained
by AutoInstall.



 236) What are the objects APPS schema contain. Ans:- The APPS schema contains synonyms to all tables and
sequences as well as all server–side code (stored procedures, views,
and database triggers).
For ERP applications, data partitioning is performed by database
views. These views reside in the APPS Oracle schema and derive the 
63 appropriate operating unit context from an RDBMS variable. 237)What are the names of the parameters u pass to the Procedure which u register in the apps? B. 1) retcode in varchar2
2) errbuf in varchar2 


238) What is application short name for General Ledger you specify in FND FLEXSQL user exit? A. SQLGL 239)How do you set profile in oracle applications In Application Developer responsibility? A Open „Profile‟ Function 


240) What is the syntax for loading data through SQL * Loader from multiple files simultaneously A. Sqlldr scott/tiger@orcl control = ctlfile
parfile -- parameter file: name of file that contains parameter specifications
parallel -- do parallel load (Default FALSE) 


241)Give the relation between categories and items table. MTL_SYSTEM_ITEMS
MTL_CATEGORIES_B
Relation INVENTORY_ITEM_ID 


242)In which tables are the categories of an item stored. MTL_CATEGORIES_B
MTL_ITEM_CATEGORIES


 243)Significance of ALL in apps tables. Tables which are related with Multiorg is suffixed with ALL. 


244)Explain about flexfield in GL.In what way it is useful? A KFF is a set of segments, each segment will identify a unique characterstic of an entity. it can be termed as intelligent key. we can define our business requirements without doing any programming.
A DFF is a set of segments which can be used to capture extra info. without any customisation


245)Execution methods?
Ans. 
a. Host b. Immediate
c. Java Stored Procedure
d. Java Concurrent Program
e. Multi Language Function
f. Oracle Reports
64 g. PL/SQL Stored Procedure
h. Request Set Stage Function
i. Spawned
j. SQL*Loader
k. SQL*Plus 


246) 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.

1. Designing New Forms, Programs and Reports
2. Forms and Reports customization
3. Developing Interfaces
4. Developing PL/SQL stored procedures
5. Workflow automations
Role of System Administrator:
1. Define Logon Users

6. Cloning of OA 



248)What are Flexfields?
Ans. 
A Flexfield is a customizable field that opens in a window from a regular Oracle Applications window. Defining flexfields enables you to tailor Oracle Applications to your own business needs. By using flexfields, 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 Flexfields: You use key flexfields to define your own structure for many of the identifiers required by Oracle Applications. Profile – „Flexfields:Open Key Window‟ (FND_ID_FLEXS)
65 Descriptive Flexfield: You use descriptive flexfields to gather additional information about your business entities beyong the information required by Oracle Applications. Profile – Flexfields: Open Descr Window‟ (FND_DESCRIPTIVE_FLEXS)



 249) Request Set and where do you define it?
Ans. 
Request sets allow you to submit multiple requests together using multiple execution path. A request set is a collection of reports and /or programs that are grouped together. A stage is a component of a request set used to group requests within the set. All of the requests in a given stage are executed in parallel. Advantages of stages are the ability to execute several requests in parallel and then move sequentially to the next stage.
Responsibility: System Administrator
Nav: Concurrent -> Set


250)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. 


251)Registration of PL/SQL with parameters? 
Ans. 1. Create the procedure in the module specific schema.
2. Create a public synonym for that procedure in the Apps schema.
3. Create the executable for that procedure.
4. Create a concurrent program.
5. Attach the concurrent program to that procedure.
Note: There are two mandatory parameters 1. Errbuf 2. Retcode. Any parameter which are to be passed should be succeeded with these two parameters and have to be registered. When calling the procedure, these two parameters are not mentioned. 

252)Value Sets?
Ans. 
Oracle Application Object Library uses values, value sets and validation tables as important components of key flexfields, descriptive flexfields, FlexBuilder, and Standard Request Submission. When you first define your flexfields, 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 flexfield segment structures. You typically define your individual values only after your flexfield 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 flexfield.
You can share value sets among segments in different flexfields, segments in different structures of the same flexfield, and even segments within the same flexfield structure. You can share value sets across key and descriptive flexfields. You can also use value sets for report parameters for your reports that use the Standard Report Submission feature.
