The Requisition application is used for creating and submitting purchase requests. It enables employees to request goods or services needed for their job roles. Once a requisition is submitted, it goes through an approval process before a purchase order is created.

In Oracle Fusion Cloud Procurement, a planned purchase order is not a valid type of purchase order. The valid types of purchase orders are standard purchase orders, blanket purchase agreements, and contract purchase agreements. Planned purchase orders are used in other procurement systems, but not in Oracle Fusion Cloud Procurement.

Project Costing is a module in Oracle Fusion Cloud Procurement that allows users to track and manage project-related expenses and revenue. It provides features for cost management, budgeting, billing, and analysis related to projects. By using Project Costing, organizations can effectively monitor and control project costs and ensure accurate financial reporting.

The "Manage Supplier Profiles" feature in Oracle Fusion Cloud Procurement enables procurement managers to create and maintain supplier profiles, approve them after review, and also provides a view of supplier profile history. This feature allows for efficient management of supplier information and ensures accurate supplier data within the procurement system.

The Default Roles feature in Oracle Fusion Cloud Procurement is used to set up default roles for all users in the procurement system. These roles are then automatically assigned to new users based on their assigned job or position. It helps streamline user access provisioning and ensures consistent role assignments across the organization. Assigning specific roles to supplier users during registration, automatically assigning roles to buyers, and granting temporary access to additional roles are separate processes and functionalities within the system.
