In Oracle Cloud Project Portfolio Management (PPM), the Organization Tree (also known as the Organization Hierarchy) is the backbone of the entire module. It defines how your business units, departments, and divisions structurally relate to each other.
Without a properly
defined and active organization tree, Oracle Projects cannot route costs,
validate resource assignments, or aggregate financial reporting.

The Dual Role of Organizations in Oracle Projects
Oracle Projects
requires you to build an organization tree because any single department or
node in that tree typically plays one of two critical roles:
· Project and Task Owning Organization: These are the specific departments in the
tree authorized to execute work and hold the financial budgets for projects.
· Project Expenditure Organization: These are the departments that
"own" resources (employees or equipment) or incur expenses (like
purchasing materials).
Why the Organization Tree is Critically Important
The organization tree
dictates four foundational behaviors in the application:
1. Driving Project Financial Reporting and Roll-ups
When you view
financial performance metrics, you rarely want to look at just one tiny
department. Executive leadership needs to see data aggregated by division,
country, or region.
· How it works: The hierarchy allows a cost or revenue
transaction incurred at the lowest department level (e.g., "Electrical
Engineering") to automatically roll up to parents higher in the tree
(e.g., "Engineering Division" $\rightarrow$
"Fremont Corporation").
2. Determining Cross-Charge and Intercompany Billing
When an employee from
Department A works on a project owned by Department B, Oracle Projects uses the
organization tree to evaluate if an internal loan or an internal invoice needs
to be generated.
· How it works: The system looks at where both organizations
sit on the tree. If they belong to different legal entities or different
business units under the tree branch, Oracle triggers automatic cross-charging
or intercompany billing rules to move the costs seamlessly.
3. Defining Transaction and Burdening Validation
Organizations inherit
rules based on their location in the tree. You can restrict certain expenses to
only be allowed by specific branches of your business.
· How it works: When a corporate expense is entered, Oracle
checks the organization tree to ensure the department is explicitly classified
as an Expenditure Organization. If it isn't listed or active
in the tree, the transaction is rejected instantly, preventing bad financial
data.
4. Managing Resource Management and Security
The organization tree
controls who can see what. Resource managers use the tree branches to define
their "pool" of available employees.
· How it works: If a manager owns the "Fremont
Engineering" branch, they automatically gain visibility over resources in
the sub-branches (Electrical, Mechanical, Structural) for scheduling and
project staffing without requiring separate security profiles for every
sub-department.
⚠️ Common Pitfall: The "Flattening"
Requirement
Because the
organization tree handles real-time transaction routing, Oracle cannot navigate
a complex, deep tree dynamically for every single line item entry—it would slow
down the system performance.
This is why Oracle
utilizes a mandatory database architecture step: Flattening.
Whenever you modify
your organization tree structure (adding a department or moving a branch), you
must run the Row Flattening and Column Flattening
utilities in Manage Organization Trees, followed by the Submit Process to Maintain Project Organizations
scheduled process. This converts the visual tree into a high-speed lookup table
that Oracle PPM uses to execute processing rules.
