Interview Questions

Which is the most commonly used package in apps that uses Autonomous Transaction?
FND_LOG, this is used for debugging. This has a procedure named string, which does a commit. Hence your debug messages are not lost in the event of rollback during unhandled exception.

What is one of the limitations of Forms Personalization?
You cannot display interactive messages as you can using fnd_message.

How to use  Flexfields in reports  ?
Ans : Most common way is to use FND user exits provided by oracle applications.
Other way is to directly use the DB views (TableName  || ‘_KFV’ or ’_DFV’) created by apps, and use the concatenated_segments column which holds the concatenated segments of the key or descriptive flexfields.

What are Autonomous transactions ? Give a scenario where you have used Autonomous transaction in your reports ?
Ans: An autonomous transaction is an independent transaction started by another transaction, the main transaction. Autonomous transactions let you suspend the main transaction, do SQL operations, commit or roll back those operations, then resume the main transaction.
Once started, an autonomous transaction is fully independent. It shares no locks, resources, or commit-dependencies with the main transaction. So, you can log events, increment retry counters, and so on, even if the main transaction rolls back.

More important, autonomous transactions help you build modular, reusable software components. For example, stored procedures can start and finish autonomous transactions on their own. A calling application need not know about a procedure's autonomous operations, and the procedure need not know about the application's transaction context. That makes autonomous transactions less error-prone than regular transactions and easier to use.

Furthermore, autonomous transactions have all the functionality of regular transactions. They allow parallel queries, distributed processing, and all the transaction control statements including SET TRANSACTION.

Scenario : You can use autonomous transaction in your report for writing error messages in your database tables.

What is record group ?
Ans: Record group are used with LOVs to hold sql query for your list of values. The record group can contain static data as well it can access data from database tables thru sql queries.

What is a FlexField ? What are Descriptive and Key Flexfields ?
Ans: An Oracle Applications field made up of segments. Each segment has an assigned name and a set of valid values. Oracle Applications uses flexfields to capture information about your organization.

What are different report triggers and what is their firing sequence ?
Ans. : There are five report trigger :
·         Before Report
·         After Report
·         Before Parameter Form    
·         After Parameter Form
·         Between Pages

The Firing sequence for report triggers is
        Before Parameter Form – After Parameter Form – Before Report – Between Pages – After Report.

What is the use of cursors in PL/SQL ? What is REF Cursor ?
Ans. : The cursor are used to handle multiple row query in PL/SQL. Oracle uses implicit cursors to handle all it’s queries. Oracle uses unnamed memory spaces to store data used in implicit cursors, with REF cursors you can define a cursor variable which will point to that memory space and can be used like pointers in our 3GLs.

How to attach reports in Oracle Applications ?
Ans:  The steps are as follows :
·         Design your report in D2K
·         Generate the executable file of the report as .rdf.
·         Move the executable as well as source file to the appropriate product’s folder.
·         Register the report as concurrent executable.
·         Define the concurrent program for the executable registered.
·         Add the concurrent program to the request group of the responsibility.

What is the use of triggers in Forms ?
Ans : Triggers are used in forms for event handling. You can write PL/SQL code in triggers to respond to a particular event occurred in your forms like when user presses a button or when he commits the form.
The different type of triggers available in forms are :
·         Key-triggers
·         Navigational-triggers
·         Transaction-triggers
·         Message-triggers
·         Error-triggers
·         Query based-triggers

What is the use of Temp tables in Interface programs ?
Ans : Temporary tables are used in Interface programs to hold the intermediate data. The data is loaded into temporary tables first and then, after validating through the PL/SQL programs, the data is loaded into the interface tables.

What are the steps to register concurrent programs in Apps ?
Ans : The steps to register concurrent programs in apps are as follows :
·         Register the program as concurrent executable.
·         Define the concurrent program for the executable registered.
·         Add the concurrent program to the request group of the responsibility

How to pass parameters to a report ? do you have to register them with AOL ?
Ans: You can define parameters in the define concurrent program form. There is no need to register the parameters with AOL. But you may have to register the value sets for those parameters.

Do you have to register feeder programs of interface to AOL ?
Ans : Yes ! you have to register the feeder programs as concurrent programs to Apps.

What are forms customization steps ?
Ans:  The steps are as follows :
·         Copy the template.fmb and Appstand.fmb from AU_TOP/forms/us.Put it in custom directory. The libraries (FNDSQF, APPCORE, APPDAYPK, GLOBE, CUSTOM, JE, JA, JL, VERT) are automatically attached .
·         Create or open new Forms. Then customize.
·         Save this Form in Corresponding Modules.

What is Key and Descriptive Flexfield.
Ans : Key Flexfield: #unique identifier, storing key information
                                      # Used for entering and displaying key information.
                   For example Oracle General uses a key Flexfield called Accounting
                   Flexfield to uniquely identifies a general account.

             Descriptive Flexfield: # To Capture additional information.
                                                   # to provide expansion space on your form
                                                       With the help of [] . [] Represents descriptive

Difference between Key and Descriptive Flexfield?
Ans :
Key Flexfield
Descriptive Flefield
1. Unique Identifier
1.To capture extra information
2. Key Flexfield are stored in segment
2.Stored in attributes
3.For key flexfield there are flexfield Qualifier and segment Qualifier
3. Context-sensitive flexfield is a feature
 of DFF. (descriptive flexfield)

What are the steps in Customer Interface?
Ans: TCA APIs need to call in this.

How to handle errors in Customer interface?
Ans: You need to Use SAVEPOINT and rollback to get all record from TCA whenever it gets the error or fail in any api. After it passes all API finally u need to commit that customer repord.

What was your role in Customer Interface?
Ans:  I have prepared custom package for Customer interface with all APIs provided by oracle. Prepared documentation too.

What is the use of CUSTOM Library in Oracle Apps?

Can you call APPCORE library in CUSTOM library ?
Ans : you cannot attach the APPCORE library to CUSTOM because it would cause a recursion problem    
          (because CUSTOM is attached to APPCORE). As of Oracle Applications Release 11i, you may
           attach the APPCORE2 library to CUSTOM. The APPCORE2 library duplicates most APPCORE  
           routines with the following packages:
·         APP_DATE2
·         APP_SPECIAL2
These packages contain the same routines as the corresponding
           APPCORE packages. Follow the documentation for the corresponding
           APPCORE routines, but add a 2 to the package names.

Can you use REF cursors in CUSTOM library?

What is FlexField?
Ans: Oracle Application uses Flexfield to capture information about
             Your organization. Flexfield have flexible structure for storing key information.
              Like Company, Cost Center, and Account. They also give u highly adaptable
               Structure for storing customized information in oracle Applications.

What are User Exits and what are different types of User Exits in Oracle Apps ?

What is MRC and what are it’s use?
Ans: The Multi Reporting Currency Feature allows you to report and maintain records at the transaction level in more than one functional currency. You can do by defining one or more set of books in addition to primary set of books.

How many reporting currencies can be attached to Primary Set Of Books ?

What are the new features in Release 11I ?

What are ad-hoc reports ?
Ans: Ad-hoc Report is made to meet one-time reporting needs. Concerned with or formed for a particular purpose. For example, ad hoc tax codes or an ad hoc database query
