Oracle Workflows Access Protection Concepts

Oracle Workflows Access Protection Concepts
As a workflow developer, you can use access protection to allow or discourage “customers” of your workflows from modifying your “seed data” workflow definitions.

As a customer of predefined workflows provided by Oracle, you can use access protection to preserve valid customizations you have made to a predefined workflow during a workflow definition upgrade.
