CAD Exam Dumps : Certified Application Developer - ServiceNow

In ServiceNow, UI Actions are elements such as buttons, links, and context menu items that allow users to perform actions on records or lists. The three valid UI Action types are:

1. List Banner Button (Option A)

Description: A button that appears in the list view header, allowing users to trigger an action affecting multiple records at once.

Example: A "Bulk Approve" button that processes selected records.

2. Form Button (Option B)

Description: A button that appears on a form, allowing users to trigger actions related to the current record.

Example: A "Submit for Approval" button on an incident form.

3. Record Navigation Button (Option D)

Description: A button that helps users navigate between related records.

Example: A "Go to Parent Record" button that redirects users to a linked record.

Incorrect Options:

Form Choice (Option C):

Not a UI Action type. Choices are typically used in choice fields (dropdowns) rather than UI actions.

List Choice (Option E):

Not a valid UI Action type. Similar to "Form Choice," it pertains to field options rather than UI elements.

Workflow Action (Option F):

Workflows are process automation tools, not UI Actions. They are not directly related to buttons or links that users interact with.

In ServiceNow, when a table is extended from a parent table, it inherits all fields from the parent. These inherited fields are integral to the structure of the child table and maintain the relationship between the parent and child tables. As a result, inherited fields cannot be deleted from the child table.

Key Points:

Inheritance Structure: The child table's structure is designed to include all fields from the parent table to preserve data integrity and ensure consistent behavior across the hierarchy.

System Constraints: ServiceNow does not provide an option to remove inherited fields from the child table. Attempting to delete such fields would disrupt the inheritance model and potentially cause system inconsistencies.

Alternative Approaches: While you cannot delete inherited fields, you can manage their visibility:

Form Layout: Adjust the form layout to hide inherited fields that are not relevant to users interacting with the child table.

Access Controls: Implement access controls to restrict visibility or edit permissions for specific fields based on user roles.

The Form Designer is a tool that allows you to create and customize forms on the ServiceNow platform. The Form Designer has four main components:

Form layout: The form layout shows the preview of the form and allows you to drag and drop fields, sections, and related lists onto the form. You can also resize, reorder, and delete the elements on the form layout.

Page header: The page header shows the name of the table and the form that you are editing. You can also access the form properties, save the form, and switch to the form view from the page header.

Field navigator: The field navigator shows the list of available fields for the table and allows you to search, filter, and add fields to the form. You can also create new fields and edit existing fields from the field navigator.

Schema map: The schema map is not part of the Form Designer. The schema map is a separate tool that shows the relationships between tables and fields on the platform. You can access the schema map from the System Definition > Tables module or from the context menu of a table.
