The expenditure type class that is recommended for the expenditure types that need to be defined for work order labor and equipment resource transactions is Work In Process. This class indicates that the transactions are related to work orders that are performed as part of a project-driven supply chain solution. This class also allows the transactions to be processed by Oracle Fusion Manufacturing applications and transferred to Oracle Fusion Project Costing applications. Supplier Invoice is not a valid expenditure type class for work order labor and equipment resource transactions. This class indicates that the transactions are related to supplier invoices that are entered in Oracle Fusion Payables applications and transferred to Oracle Fusion Project Costing applications. Usages is not a valid expenditure type class for work order labor and equipment resource transactions. This class indicates that the transactions are related to material usages that are entered in Oracle Fusion Inventory Management applications and transferred to Oracle Fusion Project Costing applications. Inventory is not a valid expenditure type class for work order labor and equipment resource transactions. This class indicates that the transactions are related to inventory movements that are entered in Oracle Fusion Inventory Management applications and transferred to Oracle Fusion Project Costing applications. https://docs.oracle.com/en/cloud/saas/project-portfolio-management/20c/oapfm/manage-project-costs.html#OAPFM2356311

10-10-10-10-10-10-10-10-10-10
Prorated Even
Linear distribution of financial or project plan values across periods, with an exception of the first period and last period in the financial plan. Financial or project plan values for the first period and last period are prorated based on the number of days in the period.

Back Loaded
Back-loaded distribution of financial or project plan values across periods. Assigned amounts increase over succeeding periods.

Front Loaded
Front-loaded distribution of financial or project plan values across periods. Assigned amounts decrease over succeeding periods.

S Curve
S-shaped distribution of financial or project plan values across periods.

Bell Curve
Bell-shaped distribution of financial or project plan values across periods. Assignment of plan values is highest in the middle periods.

Daily Spread Analysis
Spread is based upon the number of days in each financial period throughout the duration of the task assignment. Amounts are proportionally distributed throughout all periods for the duration of the task assignment None

The recommendation for this scenario is to define one business unit and two project units. A business unit is an organization that performs one or many business functions such as transaction processing or reporting. A project unit is an organization that manages projects within a business unit or across multiple business units. By defining one business unit and two project units, you can meet the following requirements of the client organization:
The management reporting and transaction processing requirements are the same for both the organizations: This can be achieved by using the same business unit for both the organizations, as the business unit determines the common setups such as ledger, currency, calendar, etc. for transaction processing and reporting.
The project planning, management, analysis and reporting requirements are different for each organization: This can be achieved by using different project units for each organization, as the project unit determines the specific setups such as project types, templates, options, etc. for project planning, management, analysis and reporting. Defining two business units and two project units is not recommended for this scenario, as this would create unnecessary duplication of setups for transaction processing

Authorization Policy Manager (APM)
APM greatly simplifies the creation, configuration, and administration of application policies APM does not support the management of users and external roles; these artifacts can only be viewed with the tool. Their provision and management is typically accomplished using Oracle Identity Manager Oracle Identity Manager (OIM) In regard to enterprise users and external roles, Authorization Policy Manager provides viewing and searching functionality only. To manage users and external roles, use Oracle Identity Manager or some other identity management tool.
OIM provision users, roles, and defines what a user can do in Oracle Cloud Duty Roles are mapped to jobs and assigned access privileges (Data Security)
