Oracle APPS: what is Mutli ORG?

Multiorg :
=============
Use a single installation of any Oracle Applications product to
support any number of organizations, even if those organizations
use different sets of books.

BusinessGroup (HRMS=>Workstructure=>Organization=Description)
Set of Books  (GL=>Setup=>Financials=>Books=>Define)
Legal Entity
Operating Unit
Inventory Organization
Sub Inventory     (Inventory=.Setup=>organizations=>SubInventories)
Stock Locations   (Inventory=.Setup=>organizations=>Stock locatiors)
Items

Major Features
===============
1)Multiple Organizations in a Single Installation

2)Secure Access
    You can assign users to particular organizations. This ensures accurate
    transactions in the correct operating unit.

3)Multiple Organizations Reporting

You can set up your Oracle Applications implementation to allow
reporting across operating units by setting up the top reporting level.
You can run your reports at the set of books level, legal entity level, or
operating unit level

Business Group:
===============
The business group represents the highest level in the organization
structure, such as the consolidated enterprise, a major division, or an
operation company. The business group secures human resources
information. For example, when you request a list of employees, you
see all employees assigned to the business group of which your
organization is a part.

Set Of Books:
============
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 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.


Legal Entity:
=============
A legal company for which you prepare fiscal or tax reports. You
assign tax identifiers and other legal entity information to this type of
organization.

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 a department. An operating unit is associated with a legal entity.
Information is secured by operating unit for these applications. Each
user sees information only for their operating unit.

Inventory Organization:
=======================
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, Work in Process,
Master Scheduling/MRP, Capacity, and Purchasing receiving functions.

Subinventory:
=============
Which is another organization inside of the Inventory oganization will
be used to define the locations under these location items will be placed.


Multiorg Table:
===============
It is a table contains the data which is relted to multiple operating units
all the multiorg table names will be end with '_ALL'.

like  PO_HEADER_ALL
      PO_LINES_ALL
      AP_CHECKS_ALL  and so on

Note: In all these tables we will find one common column called "ORG_ID"
  This column will be populated internally by the system as per the User Operating
  Unit ID

Client_Info:
===========
It is one  the RDBMS vaiabel which contains the User Operating Unit value (ORG_ID)

Multiorg View:
=================
It is a view which is created based on the Multiorg table which contains the WHERE
clause WHERE Org_ID = :Client_Info.

Note: While development of RICE Components we are suppose to Use Multiorg Views
      not Multi Org Tables.

Because if we use Multiorg tables we will get all the operating units data
if we use multiorg view we will get the operating units data which is related for that
perticular user .
