The following is the brief about the Multi-Org.

Multi-Org is a server side enhancement, which enables the Multiple Organizations in an

enterprise to use a single installation of Oracle Applications products while keeping transacting

data separate and secure

In 11i the Multi-Org Structure

Business Group -> Set of Books -> Legal Entity -> Operating Unit -> Inventory Organization

In R12 the Multi-Org Structure

Business Group -> Ledgers -> Legal Entity -> Operating unit -> Inventory Organization

The difference in 11i and R12 is : Set of Books are replaced by ledgers in R12. Ledgers arecreated using Accounting Setup Manager. Further Operating Unit can also be created in

Accounting Setup Manager itself.

division. Multiple ledgers can share the same Business Group if they share the same BusinessGroup attributes, including HR Flexfield structures.

In R12 we have a feature call MOAC(Multi-Org Access Control) which allows the user to

submit requests, enter, view and access data of different Operating Unit without having to switchbetween responsibilities.

Profile Options:

MO: Operating Unit - It will restrict the access through responsibility to only one Operating Unit

MO: Security Profile - It enables the user to get access on more than one Operating Unit by

defining a security profile with Multiple Operating Unit and assigning it to the responsibility (IfMO: Security Profile is set, then MO: Operating Unit is ignored by the system)

MO: Default Operating Unit - It is used when we have more than one OU attached to aresponsibility through security profile, among whihc you want a particular OU to be defaulted

during transaction entry stages. When the responsibility is assigned with only one OU then thatwill become the default OU, without setting the profile option MO: Default Operating Unit

HR: User Type - It limits the access on windows shared Oracle Human Resources and Other

Applications

HR: Business Group - We associate a Business Group with a responsibility using this profile

option. It should be done for all responsibilities

HR: Security Profile - When we define a new Business Group instead of modifying the

predefined setup Business Group, you need to set the HR: Security Profile option to point the

Security profile for the new Business Group. Oracle HRMS automatically creates a securityprofile with the Business Group name when you define a new Business Group
