23. What is the reason for not getting any data when a multi-org view is quired?


  • To get the data correctly, the xxx-ALL must be referenced and the ORG_ID value should be specified to extract portioned data.
  • Multiorgan views are partitioned by using ORG_ID.
  • So access through multi-org views will not return any roes, as the CLIENT_INFO Value is not set
  • Use HR_OPERATING UNITS to identify the organization _id of the OU on which query is based.
  • Use FND_CLIENT_INFO package to set the value in CLIENT INPO using set_org_contest.
  • Execute fnd_client_info. Set_org_context („?);

For example, you could define a value set to contain values that are character strings, validated from a table in your application. You can Specify that Oracle Application Object Library uses the same value set to validate different Report parameters. You can also use value sets that you use in your flex fields to validate Your report parameters.

51. What is the difference between the Operating Unit and Inventory Organization?

Ans: Operating Unit: An Organization that uses Oracle Cash Management, Order Management, and Shipping Execution, Oracle Payables, Oracle Purchasing, and Oracle Receivables. It may be a sales office, a division, or an adept.

An operating unit is associated with a legal entity. Information is secured by the operating unit for these applications. Each user sees information only for their operating unit. To run any of these applications, you choose a responsibility associated with an organization classified as an operating unit.

An organization for which you track inventory transactions and balances, and/or an organization that manufactures or distributes products. Examples include (but are not limited to) manufacturing plants, warehouses, distribution centers, and sales offices.

The following applications secure information by inventory organization: Oracle Inventory, Bills of Material, Engineering, and Work in Process, Master Scheduling/MRP, Capacity, and Purchasing receiving functions. To run any of these applications, you must choose an organization that has been classified as an inventory organization.

52. What is a Set of Books?

Ans: A financial reporting entity that uses a particular chart of accounts, functional currency, And accounting calendar. Oracle General Ledger secures transaction information (such as journal entries and balances) by a set of books. When you use Oracle General Ledger, you choose a responsibility that specifies a set of books. You then see information for that set of books only.

53. What is the Item Validation Organization?

Ans: The organization that contains your master list of items. You define it by setting the OM: Item Validation Organization parameter. You must define all items and bills in your Item Validation Organization, but you also need to maintain your items and bills in separate organizations if you want to ship them from other warehouses.


54. What is the difference between key flexfield and Descriptive flexfield?

Ans: Key Flexfield is used to describe unique identifiers that will have a better meaning than using number IDs. e.g a part number, a cost center, etc Dec Flex is used to just capture extra information.

Key Flexfields have qualifiers whereas Desc Flexfields do not. Dec Flexfields can have context-sensitive segments while Key flexfields cannot.
And one more difference that KFF displays like text items but DFF displays like [ ].

55. Which procedure should be called to enable a DFF in a form?



56. Which procedure should be used to make the DFF read-only at run time?



57. What is the difference between the flexfield qualifier and the segment qualifier?

Ans: Flexfiled qualifier identifies segment in a flexfield and segment qualifier identifies value in a segment.
There are four types of flex field qualifier

  • Balancing segment qualifier
  • cost center
  • natural account and
  • intercompany

segment qualifier:

  • allow budgeting
  • allow posting
  • account type
  • control account and
  • reconciliation flag

58. Where do concurrent request log files and output files go?

Ans: The concurrent manager first looks for the environment variable $APPLCSF If this is set, it creates a path using two other environment variables:


It places log files in


Output files go in


So for example, if you have this environment set:

$APPLCSF = /u01/appl/common $APPLLOG = log $APPLOUT = out 

The concurrent manager will place log files in /u01/appl/common/log, and output files in /u01/appl/common/out Note that $APPLCSF must be a full, absolute path, and the other two are directory names. If $APPLCSF is not set, it places the files under the product top of the application associated with the request.

So for example, a PO report would go under


Logfiles go to


Output files to


Of course, all these directories must exist and have the correct permissions. Note that all concurrent requests produce a log file, but not necessarily an output file.

59. How do I check if Multi-org is installed?


If MULTI_ORG_FLAG is set to ‘Y’, Then its Multi Org.

60. Why does Help->Tools->Examine ask for a password?

Ans: Navigate to the Update System Profile Screen. ( navigate profile system)

  • Select Level: Site
  • Query up Utilities: Diagnostics in the User Profile Options Zone.
  • If the profile option Utilities: Diagnostics is set to NO, people with access to the Utilities Menu must enter the password for the ORACLE ID of the current responsibility to use Examine. If set to Yes, a password will not be required.

61. How an API is initialized?


( user_id => p_user_id , resp_id => p_resp_id , resp_appl_id => p_resp_appl_id)

62. How do u register a concurrent program from PL/SQL?


apps.fnd_program.executable_exists -> To check if executable file exists
apps.fnd_program.executable -> To make executable file
fnd_program.program_exists -> To check if program is defined
apps.fnd_program.register -> To register/define the program
apps.fnd_program.parameter -> To add parameters
apps.fnd_program.request_group -> To add to a request group

63. How do you register a table & a column?


EXECUTE ad_dd.register_table( ‘GEMSQA’, ‘gems_qa_iqa_lookup_codes’, ‘T’, 512, 10, 70);
EXECUTE ad_dd.register_column(‘GEMSQA’, ‘gems_qa_iqa_lookup_codes’, ‘LOOKUP_CODE’, 1, ‘VARCHAR2’, 25, ‘N’, ‘N’);

64. What are the supported versions of Forms and Reports used for developing Oracle Applications Release 11?

Ans: The following supported versions are provided in Developer/2000 Release 1.6.1:

  • Forms 4.5
  • Reports 2.5

65. What is the Responsibility / Request Group?

Ans: Responsibility is used for security reasons like which Responsibility can do what type of jobs etc. Set of Responsibilities is attached with a Request group. When we attach the request group to a concurrent program, that can be performed using all the Responsibilities that are attached with the Request group.

66. What is DFF?

Ans: The Descriptive Flexi field is a field that we can customize to enter additional information for which the Oracle Apps product has not provided a field.

Ex. ATP program calculates for those warehouses where Inventory Org Type is DC or Warehouse in DFF Attribute11 of MTL_PARAMETERS table.

67. What is multi-org?

Ans: It is data security functionality in Oracle 10.6 and above. Applicable User responsibilities are created and attached to a specific Operating Unit. Users can access the data that belongs to the Operating unit they log in under. 40

The benefit is it enables multiple operating units to use a single installation of various modules while keeping transaction data separate and secure by the operating unit.

It has an effect on the following modules:

  • Order Entry
  • Receivable
  • Payable
  • Purchasing
  • Project Accounting
