Differences Between Using Page Composer and Application Composer

You can use multiple tools to configure the UI. This topic highlights the differences between the types of configurations you can do using Application Composer and Page Composer.

Key Differences

Basis of Comparison	Page Composer	Application Composer
Configuring the page you're viewing	Configure a UI page you're viewing and see your changes reflected immediately on that page. You can use Page Composer to make changes to one page at a time. For example, if you make a field required on the Edit Infolets page, the field isn't automatically required on the Create Infolets page.	You make your configurations in Application Composer. You can then test your work by navigating to the appropriate page. Because you use Application Composer to configure application objects, if you make a field required, it affects all interfaces where that field appears.
Supported interfaces	Application UI	Application UI Mobile Microsoft Outlook
Creating your own fields and application objects	Not supported.	You can add custom fields and entirely new objects.
Creating saved searches	Create and edit saved searches for users. The saved searches provide saved search criteria to speed up common searches. You can also use them as filters in actionable infolets.	Not supported.
Tailoring your configurations for users with different job roles	Supports different levels of configurations for application pages.	Supports configurations by job role or for all users.
Configuring external-facing partner pages	You must use Page Composer to configure all external-facing partner pages, such as the partner registration page and the partner portal landing page.	You must use Application Composer to configure only for partner pages internal to your organization, such as the partner Overview page.

What You Can't Do in Page Composer

Using Page Composer, you can't do these tasks:

• Change either the data or functional security for a page. While you can hide some components, you must change the security setup to control access.

• Filter or reorder lists of values.

• Add any code, validation logic, or scripting to the buttons or fields.

• Add call outs to other APIs to populate fields with values.

• Change the selections that appear in the Navigator menu.

• Configure the Search region inside Search and Select dialog box.
