The Bar Chart and Pie Chart report types can be created by right-clicking on a column header in a table’s list. These report types show how individual pieces of data relate to the whole using proportional bars or slices. You can also choose different aggregation methods such as count, sum, average, min, max, or percent. Reference: [Create reports from lists]

Inbound Action scripts are server-side scripts that run when an email is received by the system. They can use the current object to access the record that is created or updated by the email, and the email object to access the properties and methods of the email message. The previous and event objects are not available in Inbound Action scripts. The producer object is only available in Record Producer scripts, which are used to create records from a service catalog item.

A Module Link type defines how the module opens in the content pane when the user clicks on it in the navigation pane1. The URL (from Arguments) link type allows you to specify a URL that opens the Application Properties page for the selected application2. The URL can include arguments that are evaluated at runtime, such as the application name or scope3.

A possible reason to build a custom app is to fulfill a specific use case on internal processes. For example, you may want to digitize a manual process that is not covered by an existing ServiceNow solution, such as managing inventory, tracking expenses, or scheduling events. Building a custom app on the Now Platform can help you automate workflows, improve data quality, and provide better user experiences. The other options are not valid reasons to build a custom app. To avoid using a code repository like GitHub or GitLab is not a reason to build a custom app, as you can still use source control integration with your custom app development. To create a custom integration for a 3rd party system is not a reason to build a custom app, as you can use integration tools such as IntegrationHub or REST APIs to connect with external systems without creating an app. To replace ServiceNow base tables is not a reason to build a custom app, as it is not recommended to modify or delete base tables that are essential for ServiceNow functionality.

https://docs.servicenow.com/bundle/paris-servicenow-platform/page/administer/flow-designer/concept/spokes.html

A spoke is a scoped application containing Flow Designer content dedicated to a particular application or record type. Flow Designer provides a set of core actions to automate Now Platform® processes. You can add application-specific core actions by activating the associated spoke.

User-defined non-inherited fields can be deleted from a table in ServiceNow. These are fields that are created by users on a specific table and are not inherited from a parent table. Inherited fields cannot be deleted from a table, as they are defined on a parent table and shared by all child tables. Any field on a table cannot be deleted, as some fields are system-defined and essential for the table functionality. Table records are not deleted when a field is deleted, as the field deletion only affects the table structure and not the data. Reference: Delete fields

Flow Designer is a graphical tool that allows users to automate processes in ServiceNow without coding. The following are supported by Flow Designer:

• Call a subflow from a flow. This is a feature that allows users to invoke a subflow, which is a reusable unit of logic, from a flow. This can help simplify complex flows and avoid duplication of logic.
• Use Delegated Developer. This is a feature that allows administrators to delegate the development and maintenance of flows and actions to users who are not administrators. This can help distribute the workload and empower non-admin users to create automations.
• Run a flow from a MetricBase Trigger. This is a feature that allows users to trigger a flow based on a MetricBase query, which is a way of analyzing time-series data in ServiceNow. This can help automate actions based on data trends and patterns.

The following is not supported by Flow Designer:

• Test a flow with rollback. This is not a feature of Flow Designer, but of Automated Test Framework (ATF), which is a tool that allows users to create and run automated tests on ServiceNow applications and features. ATF supports testing flows with rollback, which means reverting any changes made by the flow during the test execution. References: Flow Designer, Automated Test Framework

When evaluating Access Controls, ServiceNow searches and evaluates:

• From the most specific match to the most generic match. This is the correct answer because ServiceNow follows a top-down approach when evaluating Access Control (ACL) rules, which are used to restrict the access to the data and functionality of the ServiceNow platform based on the user’s roles and conditions. ServiceNow starts with the most specific match, which is the field-level ACL rule, then moves to the table-level ACL rule, and finally to the global or * ACL rule. ServiceNow grants access if any of the ACL rules evaluates to true, and denies access if all of the ACL rules evaluate to false.

The following are not correct descriptions of how ServiceNow searches and evaluates Access Controls:

• Only for matches on the current table. This is not correct because ServiceNow does not only look for matches on the current table, but also on the parent tables and the global or * table. For example, if there is no ACL rule for the incident table, ServiceNow will look for an ACL rule for the task table, which is the parent table of the incident table, and then for the global or * table, which is the parent table of all tables.
• Only for matches on the current field. This is not correct because ServiceNow does not only look for matches on the current field, but also on the table that contains the field and the global or * table. For example, if there is no ACL rule for the short_description field on the incident table, ServiceNow will look for an ACL rule for the incident table, and then for the global or * table.
• From the most generic match to the most specific match. This is not correct because ServiceNow does not follow a bottom-up approach when evaluating Access Controls, but a top-down approach, as explained above. References: Access Control Rules, ACL Evaluation Order

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.

Web services are software systems that use standardized protocols and formats, such as XML and HTTP, to exchange data and messages between different applications or systems over the Internet or other networks12. Web services enable interoperability and integration among diverse software components, regardless of their programming languages, platforms, or architectures34.

Created UI policy on incident form, action set's cmdb_ci field as mandatory and script as not. result, field was not mandatory.

A UI Policy’s Actions execute before the UI Policy’s Scripts. Actions are predefined operations that can be applied to fields or sections, such as making them mandatory, read-only, visible, or setting a default value. Scripts are custom JavaScript code that can be used to perform more complex logic or validations. Actions are executed first, and then Scripts are executed if the UI Policy conditions are met. References: [ServiceNow Docs - UI policy actions], [ServiceNow Docs - UI policy scripts]

An Access Control list (ACL) defines what data users can access and how they can access it in ServiceNow tables1. The ACL evaluates the user roles and the conditions defined in the ACL rules to determine the user’s access level2. In this case, the ACL rules for the table are as follows:

• table.None read Access Control for users with the admin and itil roles: This means that users with the admin or itil roles cannot read any field in the table unless there is a more specific rule that grants them access3.
• table. * read Access Control for users with the admin role: This means that users with the admin role can read all fields in the table.
• table. field3 read Access Control for users with the itil role: This means that users with the itil role can read only the field3 in the table.

Therefore, a user with the itil role can read only the field3 in the table, and not the other fields.

The Field Watcher is a debugging tool that allows you to monitor the values of fields on a form as they change due to scripts or other actions. It can be used to debug Business Rules, Client Scripts, and Access Controls, but not Script Includes. Script Includes are server-side scripts that define reusable functions and classes. They are not associated with any specific field or form, and therefore cannot be watched by the Field Watcher.

• Field Watcher
• Script Includes

A benefit of creating an Application Properties page for each application you develop is that Application Properties allow a developer or admin to make changes to an application’s behavior without modifying application artifacts. Application Properties are system properties that store configuration information for a specific application. They can be used to control various aspects of the application, such as feature flags, default values, thresholds, or URLs. By creating an Application Properties page, you can group and display all the properties related to your application in one place and make them easy to access and update. This way, you can avoid hard-coding static data in your application code and make your application more flexible and maintainable. Reference: Working with System Properties, Organizing your ServiceNow System Properties

Application Access is a feature that allows you to control the access level of other application scopes to your application’s data tables. By setting the Accessible from field value to This application scope only, you can restrict the access to your data tables to only your application scope. This means that other application scopes cannot create, read, write, or delete records on your data tables, unless they have explicit permissions through Access Controls or other means.

From the list below, the following is a reason an application might not be a good fit with ServiceNow:

• Requires “as-is” use of low-level programming libraries. This is the correct answer because ServiceNow is a high-level platform that abstracts away the low-level details of the underlying infrastructure and technology stack. ServiceNow provides a rich set of APIs, tools, and features that allow users to develop applications without coding or with minimal coding. However, ServiceNow does not support the direct

A transform map determines the relationships between fields displaying in an Import Set table and fields in an existing ServiceNow table, such as the Incidents or Users table.

Catalog Client Scripts and Catalog UI Policies are the client-side scripts that apply to Record Producers. Catalog Client Scripts allow you to add or modify functionality on a catalog item or record producer form. Catalog UI Policies dynamically change information on a catalog item or record producer form. UI Scripts, UI Actions, Client Scripts, and UI Policies do not apply to Record Producers.

g_form.showFieldMsg("field_name", "Hello World", "error"); Puts "Hello World" in an error message **below the specified field**. g_form.addInfoMessage() or g_form.addErrorMessage() place a blue box message at the top of the screen. Pg 126 of the CAD handbook

The method that prints a message on a blue background to the top of the current form by default is g_form.addInfoMessage(). The g_form object is a global object that provides access to form fields and UI elements on a form. The addInfoMessage() method is a method of the g_form object that displays an informational message next to the form header. The message has a blue background color by default, unless it is overridden by a CSS style. The addInfoMessage() method takes one argument, which is the message text to display.

Application Access is a feature that allows you to control the access level of other application scopes to your application’s data tables. By selecting the Allow access to this table via web services option, you can enable other application scopes to access your data tables using web services, such as SOAP or REST. However, the user performing the query via web services must have the correct permissions to access the table’s records. The user must have the appropriate roles and access controls to perform the operations on the table, such as create, read, write, or delete.

The other statements are not true when this option is selected. This option does not restrict the ability to delete records via web services, nor does it allow records to be always read. The access to the records depends on the user’s permissions and the web service method. This option also does not restrict access only to SOAP web services, but applies to both SOAP and REST web services. Finally, this option is not the only way to enable web service access to the table’s records. Even when this option is not selected, users with the correct permissions can use web services to access the table’s records, as long as they specify the application scope in the web service request.

Configuring the label of a field in a child table changes the label only on that table, not on the base table or the parent table. The base table is the table that contains the common fields for all the extended tables, and the parent table is the table that is directly extended by the child table. The label of a field on the base table or the parent table can be different from the label on the child table. References: [ServiceNow Docs - Table extension], [ServiceNow Community - How to change field label in child table]

The fastest way to create and configure a Record Producer is to open the table in the Table records and select the Add to Service Catalog Related Link. This will automatically create a Record Producer with the same fields as the table and add it to the Service Catalog. You can then modify the Record Producer as needed. The other options require more steps and manual configuration. Reference: Create a record producer

The steps to import new data into ServiceNow from a spreadsheet are: Load Data, Create Transform Map, Run Transform. Load Data is the process of uploading the spreadsheet file and creating an Import Set table that contains the data to be imported. Create Transform Map is the process of defining how the fields from the Import Set table map to the fields of the target table in ServiceNow. Run Transform is the process of executing the Transform Map and copying the data from the Import Set table to the target table. Reference: Import sets, Transform maps

A workflow is a tool that allows you to automate processes on the ServiceNow platform. A workflow consists of activities and transitions that define the logic and flow of the process. A workflow context is an instance of a workflow that is generated from a workflow version, executes activities, and follows transitions. A workflow context is associated with a specific record on a table and tracks the state and progress of the workflow. You can view and manage the workflow contexts from the Workflow Contexts module or the Workflow Contexts related list on a record.

The other options are not valid definitions of a workflow context. A checked out workflow is a workflow that is being edited by a user and has not been published yet. The table and conditions for a workflow are the criteria that determine when a workflow should run on a record. The business reason or process for a workflow is the purpose and function of the workflow.

https://docs.servicenow.com/bundle/rome-application-development/page/build/applications/concept/c_ScriptProtectionPolicy.html

The following is true for a Script Include with a Protection Policy value of Protected:

• The Protection Policy is applied only if the application is downloaded from the ServiceNow App Store. This is true because the Protection Policy is a feature that allows developers to protect their Script Includes from being viewed or modified by other users when they distribute their applications through the ServiceNow App Store. The Protection Policy is only enforced when the application is installed from the App Store, not when it is developed or tested on the instance.

The following are not true for a Script Include with a Protection Policy value of Protected:

• Any user with the protected_edit role can see and edit the Script Include. This is false because the protected_edit role is not related to the Protection Policy, but to the Access Control (ACL) rules. The protected_edit role allows users to edit protected fields on a table, such as the script field on the sys_script table, which stores the Business Rules. The Protection Policy does not use roles to control access to the Script Includes, but a cryptographic key that is generated when the application is published to the App Store.
• The Protection policy option can only be enabled by a user with the admin role. This is false because the Protection policy option can be enabled by any user who has the application_admin role for the scoped application that contains the Script Include. The application_admin role grants full access to the application development and administration within the scope of the application.
• The Protection Policy is applied only if the glide.app.apply_protection system property value is true. This is false because the glide.app.apply_protection system property is not related to the Protection Policy, but to the Application Restricted Caller Access (ARCA) feature. The ARCA feature allows developers to restrict the access to the Script Includes from other applications based on the caller’s scope. The glide.app.apply_protection system property determines whether the ARCA feature is enabled or disabled on the instance. References: Script Includes, Protect Script Includes, Application Restricted Caller Access

Application developers can specify which ServiceNow page a user sees after submitting a new record using the Record Producer UI by writing a script in the Record Producer’s Script field: producer.redirect = “”;. This script sets the redirect property of the producer object to the URL of the desired page. For example, producer.redirect = “home.do”; will redirect the user to the homepage after submitting the record. The other options are not valid ways to specify the redirect page for a Record Producer. Reference: Populate record producer data and redirect users

An application admin is a role that grants full access to an application and its tables, scripts, and other components1. An application admin can create, modify, and delete any element of the application, as well as publish and install it2. An application typically has an application admin role that is automatically created and assigned to the application creator3.
