Creating Error Pages (SAP Library - Model View Controller (MVC))

Creating Error Pages

Use

If on a page that contains flow logic, a view, or a controller, a runtime error occurs, you can assign an error page to it. When a runtime error occurs during execution of this (other) page or this controller, the system automatically processes the assigned error page and sends it to the browser. If no error page is assigned to a page/a controller, in case of a runtime error the system displays a standard page. If runtime errors occur in a called controller or view and there is no error page, this section remains empty.

Prerequisites

You created the page (the controller) you want to use as error page. See also: Creating Pages or Creating Controllers.

You cannot assign an error page to a page or a controller that itself is marked as error page.

With views you must not assign a controller class, because an error page is always called implicitly by the BSP runtime.

Procedure

To identify a page / a controller as an error page:

Select the page or the controller for your BSP application.
Go to the properties display and switch to Change mode if necessary.
In section Error Handling, mark the checkbox Is Error Page.
Save your entries and activate the page or controller.

Result

You can now assign this page or controller as Assigned Error Page to another page or another controller.

Example

The BSP application ITMVC contains an example of how to implement and use an error page.
