17.3.1 About Page Processes
A page process performs an action at a specified point during the rendering or submission of the page. For example, you can create a page process to execute logic or to make a call to the Application Express engine. A page process is a unit of logic that runs when a specific event occurs, such as loading or submitting a page.
From a functional perspective, there is no difference between page-level and application-level processes. The difference between these two process types is where the process is defined, that is at the page-level or at the application level.

17.3.5 Creating Page Process Success and Error Messages
You can define both success and error messages that display when a process runs. How an error message displays depends upon the processing point. For processes with a processing point of On Submit - Before Computation and Validations
or On Submit - After Computations and Validations
, you can specify whether the error message displays inline on the current page (the default) or on a separate page. For all other page processes, error messages display on a separate error page.
To create a page process error or success message:
- View the process attributes in the Property Editor.
