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.

¶¨ÒåµÄ¹¤×÷Á÷¡£
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.

All workflow objects except lookup codes, function attributes, and message attributes contain an Access tab in their property pages.  Lookup codes, function attributes, and message attributes inherit their access settings from their parent lookup type, function, or message, respectively.

The Access tab lets you define whether:
•Future customizations to the object are preserved during a workflow definition upgrade.
•The object can be edited by users operating at a higher access level.
