Oracle Applications Interview Questions And Answers (FAQs)

1. What is dynamic sql?
Ans:- pl/sql uses early binding , so we cant execute DDL statements in pl/sql.
To over come this situation we have two options

   1> we can use EXECUTE IMMIDIATE statement
   2> we can use DBMS_SQL package

2. Tell me 5 important tables in GL (GENERAL LEDGER)
       GL_JE_HEADERS
       GL_JE_LINES
       GL_JE_BATCHES
       GL_SETS_OF_BOOKS
       GL_CODE_COMBINATIONS
       GL_PERIODS
       GL_BUDGETS

3. What are User Exits
    A user exit is a 3rd Genaration Language  program where it can be linked to the report builder executable
   There are 3 types of user interfaces

    a>  ORACLE user interfaces
    b>  OCI (Oracle Caller Interface)
    c>  None-Oracle user exit

4. What are the User Parameters in User Exits?
          srw.user_exit ('FND SRWINIT');
              user exit is the mandatory parameter in srw.user_exit

5. How many interfaces in GL, AP what are they?
    3 interfaces in GL.

6. Is it possible to use User Exits in Report builder? How.
    Yes,
   In BEFORE REPORT we call srw.user_exit ('FND SRWINIT')
   In AFTER REPORT we call srw.user_exit ('FND SRWEXIT')

7. Diff between functions and procedures
   Procedure is called as pl/sql statement
   Function is called as an expression and it can called from SELECT statement.

8. Diff between ap_invoice_all and ap_invoice
     The _all tables are sharable in multi oraganization environment and it contains ORG_ID field.
Ex: fnd_client_info.set_org_context(‘204’) ;

10. Place holder, summary columns, formulae columns?
   Place holder is a column for which you set the data type and value in PL/SQL that u define.
 This can be used in BEFORE REPORT Trigger, if the placeholder is a report level trigger.
 A report level formula column, if the place holder is a report_level column
 A formula in the placeholder's group or a group below it (The value is set only once for each record
of the group).

   A summary column can be either report level or group level is used to get the    value of built in function on a single column.

   A formula column can be either report level or group level is used to get the     values from one or more columns.

11. Multi org concepts?
        It is a server side enhancement where multiple business units can use a single Installation of oracle product.
     The architecture of multi org is, Business group, set of books, operating units,      Inventories.
  ORG_ID is stored in operation units and ORGANIZATION_ID is stored in inventories. There is one-to-many relationship between them.

12. Lexical parameters and bind parameters?
Lexical parameter is a replacement of text string in select statement, it is preceded by & (ampersand).
For this we need to create user parameter, It should be character and initialized. We need to pass the values at runtime for this lexical parameter.

 Bind parameter is a replacement of  single value or expression in select statement.         It is preceded by colon(:). It can be number, date, or character data type .It cannot be used in FROM clause.

13. How can we execute the query in the report trigger?
  Using SRW.DO_SQL we can execute the DDL and DML queries.
This procedure executes the specified SQL statement from within Report Builder.
The SQL statement can be DDL, or DML (statements that manipulate data). 

14. Firing sequence of report triggers?
  BEFORE PARAMETER FORM
  AFTER PARAMETER FORM
  BEFORE REPORT TRIGGER
  BETWEEN PAGES
  AFTER REPORT TRIGGER
 
15.key flexfield, and descriptive flexfield.
 Key flex fields captures the unique information, and descriptive flexfields captures the more information.
 The key flex field in GL is Accounting Flex Field.
 The KFF in AR are Territory and Sales tax.

16. where will you write user exits 
   The FND SRWINIT in BEFORE REPORT trigger and
   the FND SRWEXIT in AFTER REPORT trigger.

17. What is mutating table.
  A trigger is trying to modify the triggering table. To overcome this we need to use temporary table and views.

  A table in transition then we called that table is mutating.
18. What is Retcode, and Errbuff?                                                   
    These are mandatory parameters when we write concurrent program using stored procedures.

RETCODE contains 3 values 0-for sucess,1-sucess with warnings, 2-errors.
ERRBUFF contains error message.
  Concurrent manager will fill the values for these parameters.

19. Request group?
  Collection of requests, request sets and concurrent programs that a user can operate under a given responsibility.

22. What is short name, and base path?
    A short name is used to identify menus, forms, concurrent programs, and other application components.
        A base path is top directory in applications directory tree.

23.Is table registration is mandatory in apps?
    No, but when ever we use flex fields and alerts then it is mandatory.

24. What are the procedures used for registration and deletion of tables in apps?
    AD_DD.REGISTER_TABLES(appl short name,
                        table name,

                        data type,
                        Witdth,
                        nullable,
                        transferable); and optional precission.

        2> USER_SOURCE
        3> USER_ERRORS

95. What are Materialized views?

    Application short name, program name, description, start time, sub request, argument1 to argument100.

98. What is the Application Name in CP Executable and CP windows ?
   In CP Executable, Application Name determines in which directory your report executable is stored.
