Shared entities can be referenced by multiple products. These entities allow you to define broad-level structures that help you to include members when implementing the E-business suite. Which business unit will own specific data in a shared entity is at the discretion of the compnay. Employee data is always owned by human resources, provided the E-business suite is installed.

Step 1: Develop the Organization Structure
A successful implementation of Multiple Organization support in Oracle Applications depends primarily on defining your organizational structure in the multi-level hierarchy used by Oracle Applications. The levels are:
• Business groups
• Primary ledgers (as defined in Accounting Setup Manager)
• Legal entities
• Operating units
• Inventory organizations
 
Step 2: Define Accounting Setups
Use the Accounting Setup Manager in Oracle General Ledger to define accounting setups that include the following common financial components:
One or more legal entities (optional)
Primary ledger
  • Reporting Currencies (optional)
  • Balancing segment value assignments (optional)
  • Subledger Accounting Options

Operating Units (available if legal entities are assigned)
  • Intercompany Accounts (available if legal entities are assigned)
  • Intracompany Balancing Rules (optional)

Sequencing (optional)
Secondary Ledger (optional)

To use multiple organizations, you must define an accounting setup with at least one legal entity, a primary ledger that will record the accounting for the legal entity, and an operating unit that is assigned to the primary ledger and a default legal context (legal entity). It is also recommended that balancing segment values be assigned to the legal entity to help you identify legal entity transactions during transaction processing and reporting and to take advantage of Intercompany Accounting.
Note: If your enterprise structure requires that you define a business group, you should define accounting setups before business groups.
