Oracle Fusion, which is part of Oracle’s suite of applications, includes many tables and data structures for various modules and functionalities. When you refer to “ppm tables”, I assume you are referring to tables associated with the Project Portfolio Management (PPM) module in Oracle Fusion.

Below is an overview of some of the primary tables related to PPM in Oracle Fusion:

1. Project Headers: This table holds header information for projects.
2. Project Tasks: Stores task details associated with a project.
3. Project Resources: Keeps track of resources assigned to projects, whether they be human resources, machinery, etc.
4. Project Costs: Contains financial details, expenses, and other costs related to a project.
5. Project Revenue: Information regarding the revenue generated from projects.
6. Project Billing: Details about client billing and invoicing related to projects.
7. Project Budgets: Contains details about the budgeting of projects.
8. Project Forecasting: Holds data related to forecasting for projects.
9. Project Contracts: Information about contracts associated with projects.

Note: The names provided above are generalized representations of the kind of data you might find in Oracle Fusion PPM. In reality, the exact table names will have specific Oracle naming conventions, and there might be many more auxiliary and supporting tables based on functionalities like reporting, analytics, etc.

If you need to work with these tables, you’d typically use SQL queries or Oracle-provided tools and interfaces. Always remember to be cautious when working directly with database tables, especially in a production environment. Missteps can lead to data loss or inconsistencies.
