Any enterprise has several organization structures. These organizations interact with each other for various purposes. While interacting with other organizations data has to be secure and should be transferred to the correct organization.What is Multi Org
Multi Org is a feature, which helps us to classify and define various organizations in such a way that hierarchy is maintained and data is secure across organizations. It also decides how transactions flow through different organizations and how those organizations interact with each other.
The various organizations that can be defined within Oracle Applications are as follows:
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. Oracle Apps provides with a predefined Business Group ‘Setup Business Group’. Reliance Group of Companies is an example of Business Group.
GRE/Legal Entity. The company for which we prepare tax returns. You assign tax identifiers and other legal entity information to this type of organization. If there are several subsidiary companies for which tax returns are filed, each company is a separate legal entity. Reliance Group of Companies consists of several companies like Reliance Industries ltd, Reliance Info-comm, Reliance Energy ltd etc. Each company is a separate Legal Entity.
Note: The Set of Book can contain multiple Legal Entities.
Operating Unit. Each group company will have several branch offices involved with purchasing, order management, shipping execution etc. Each such branch will be an Operating Unit.
It could be a sales office, a division, or a department. An operating unit is associated with a legal entity.
For implementing Oracle Cash Management, Order Management and Shipping Execution, Oracle Payables, Oracle Projects, Oracle Purchasing, Oracle Property Manager, Oracle Receivables and Sales and Marketing Operating Unit is required.
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. Inventory organization is generally assigned to a manufacturing plant. An operating unit can also be an Inventory Organization. Many branches (operating units) might be Manufacturing Plants and will be attached to an Inventory/Warehouse. Such inventory/warehouses will be Inventory Organizations.
HR Organization. HR organizations represent the basic work structure of any enterprise. They usually represent the functional management, or reporting groups that exist within a business group.
Asset Organization. An asset organization is an organization that allows you to perform asset–related activities for a specific Oracle Assets corporate depreciation book. Any organization (legal entity, operating unit, inventory organization), which has Fixed Assets can be classified as Asset Organization. For implementing Oracle Assets, this type of organization is used.
Secure Access within Multi Org
An individual Operating Unit is assigned to an individual application Responsibility. To see and work with data that is relevant to a specific Operating Unit, users choose the appropriate Responsibility after logging on to Oracle Applications.
The current Multi-Org architecture utilizes database objects like Views to build a security layer that allows you to logically partition all your application data in one database, instead of physically partitioning data with multiple instances and even multiple application installations.
In earlier versions of Oracle Applications data partitioning was done using multiple instances and therefore installation had to be done several times for various operating units.
Note: All Multi Org tables in the database will be suffixed with ‘_ALL’.HRMS Organization Model
The business group is the largest organization unit you set up in Human Resources to represent your enterprises as an employer. After defining one or more business groups for your enterprise, you set up one or more Government Reporting Entities (GREs) within each business group. The GRE is the organization that federal, state, and local governments recognize as the employer.
The following are the summarized steps for implementing Multi-Org in Oracle Applications or when converting from a Non Multi-Org environment to a Multi-Org environment.
1.1 Develop an Organization Structure
1.2 Define Set of Books
1.3 Define Locations
1.4 Define Business Groups (Optional)
1.5 Define Responsibilities
1.6 Associate Responsibilities with Business Groups
1.7 Define Organizations
1.8 Define Organization Relationships
1.10 Convert to Multi-Org Architecture
1.11 Define Inventory Organization SecurityHow to set Org_id at back-end
We have a API to set the org_id from the backend.
Note:- Org_id indicates the "Operating Unit" in the Business Structure.
How to I know what Org_id is set at back-end
We can use userenv function to know the Org_id set at backend.
select userenv('CLIENT_INFO') from dual;
Why we need to set org_id at back-end
We usually, set org_id at back-end. So that we can get the org_id records from the Multi Organization views.
What happens if I try to query records from Multi-Origination views without setting Org_id at back-end
It will not fetch any records. As, "where" condition fails (org_id = Userenv('CLIENT_INFO'));
Note:- If you set org_id from back-end, then you get org_id value populated by above userenv function.
Is this Multi -Org concept is same for all the Oracle Application versions
No. Above Technical points are applicable only till 11i version. It is different in Release 12.
