Developers DO/DO NOT create application file records directly from the Application File table
The platform is a ____________ development environment that displays the currently selected application, identifies the scope of every application artifact, and prevent any changes that violate the access settings for an application
Application Access Settings
____________________ is similar to ACLs in that it allow you to restrict access to certain resources, but instead of restricting tables and records from users - they restrict application resources from other applications
Runtime Access tracking

ServiceNow Best Practices for Update Sets
-Do not delete update sets, if an update set is deleted, any updated record maybe overwritten in the next update
-Do not include the system_id field from the ldap_server_config record in an update set, this points to the wrong system_id for the target instance and does not work
-Do not back out the Default update set, causes damage to the system
-Never change the Update Set field value in a Customer Update record
-Do not mark an update set as Complete until it is ready to migrate. Once complete, do not change it back to "In progress".
-Do not manually merge updates into an update set, always use the Merge Update Set module
-If a committed update set has a problem in the test instance, build the fix in another update set in the development instance
-Always preview an update set before committing it
-Set completed update set on the production instance to "Ignore"
-Keep a to-do list of manual changes and data loads that need to be completed after an update set is applied
-Do not make too many changes at one time, verify that the correct changes have been made incrementally
Donuts and semi-donuts
Multilevel pivot tables
Auto Map Matching Fields
Which utility is used to determine if field names in an Import Set match the field names on the target table when importing data into ServiceNow?
Good fit for ServiceNow
-Data can be modeled in a relational database
-Extensive use of forms to interact with data
-Needs workflow to manage processes
Bad fit for ServiceNow
-Data is unstructured such as audio or video
-Requires "as-is" use of low level programmatic libraries
-Multiplayer games or apps that need a game engine
-No process flow through application
True//False: ServiceNow is good for real-time data delivery and update form external sources
True//False: ServiceNow is good for media streaming
The option in Table configuration that allows this table to be extended from
Columns, Controls, Application Access
Sections of the configuration for Table
Links available to display within application menu
_________________field on the Module form specifies what type of link the module opens.
-List of Records
-Run a Report
How to get to the mobile version of the application
Form element: Provides navigation tools and actions related to the record
Form element: Stores specific data about the record
Form element: Provides access to additional functions based on record type and system setup. Administrators can add related links to form using UI actions.
Form element: Displays records in other tables that have relationships to the current record.
Form element: Allows for editing related lists without having to navigate away from the form. Changes are saved when the form is saved.
Response time indicator
Form element: Appears at the bottom of some forms to indicate the processing time required to display the form.
Drag and drop interface used to:
-Create form layouts
-Create form views
-Create and delete form sections
-Add fields to tables
Fields, Field Types
Components of the Field Navigator
A list of all fields from the selected table that are not already part of the form layout
A list of data types that can be used to create new table fields. The Form Layout is used to create and edit fields, sections, and annotations
onLoad, onChange, onSubmit, onCellEdit
The Client Script Types:
Option in the configuration that controls whether the script is enabled. Inactive scripts do not execute.
control, oldValue, newValue, isLoading, isTemplate
The parameters for the onChange function
GlideForm (g_form) Class
______________ client-side API provides methods for managing form and form fields including methods to:
-Retrieve a field value on a form
-Hide a field
-Make a field read-only
-Write a message on a form or a field
-Add fields to a choice list
GlideUser (g_user) Class
_________________ API provides methods and non-method properties for finding information about the currently logged in user and their roles
g_user.hasRole('x_foo_app_user'), does this return true for the admin role?
Client-side debugging & UI Policies debugging
-Debugging tools built into web browsers (browser dependent)
Tracks and displays information about actions ServiceNow performs on a form field
Client-side logic which governs form and form field behavior. Unlike Client Scripts, UI Policies do not always require scripting
UI Policy Actions
Client-side logic in a UI Policy used to set three field attributes:
UI Policy Scripts
Client-side API to execute script logic based on whether the UI Policy conditions tests true or false
Two types of server-side scripts:
Server-logic which execute when database records are queried, updated, inserted, or deleted
Before, After, Async, Display
The "When" options for Business Rules:
Business Rules execute their logic before a database operation occurs
Business Rules execute their logic immediately after a database operation occurs and before the resulting form is rendered for the user
Business Rules execute asynchronously
-Business Rules execute their logic when a form loads and a record is loaded from the database
-Processed when a user requests a record form
-Primary objective is to use a shared scratchpad object, g_scratchpad, which is also sent to the client as part of the form.
Used to specify when the Business Rule script should execute
_____________ often use the current and previous objects in their script logic
•Automatically instantiated from GlideRecord class
•Properties are all fields for a record and all the GlideRecord methods
•Property values are values as they exist in the runtime environment
•Automatically instantiated from the GlideRecord class
•Properties are all fields from a record
•Property values are values for the record fields when they were loaded from the database and before any changes are made
•Not available in async Business Rules
•Examining scripts to look for errors
•Verifying the trigger is configure correctly
Business Rule debugging before has been:
Business Rule debugging strategies:
Allows direct scripting access to fields and field values on related records
GlideSystem, GlideRecord, GlideDataTime
Commonly used server-side APIs
________________ is a server-side API that:
-is used for database operations instead of writing SQL queries.
-is an object that contains zero or more records from one table
Primary strategy for debugging Business Rules and other synchronous server-side scripts
-Set, remote, and pause at breakpoints
-Step through code line by-line
-Step into and out of functions and method calls
-View the values of local, global, and private variables
-View the call Stack
Pauses script execution to give developers the chance to examine variables and their values
Reusable server-side script logic that defines a function or class
____________________ execute their scripts logic only when explicitly called by other scripts
__________________ function is both declared and invoked within the same script field. Whenever writing a script that only needs to run in a single context, such as a transform map script, use this type of function.
On demand/classes, Extend a existing class, Define a new class
Different types of Script Includes
On Demand Script Include
-A Script Include that defines a single function
-Function is callable from other server-side scripts, can never be used client-side even if the Client callable option is selected
Extend a Script Include
Script Includes can extend existing Script Includes by adding new methods and non-method properties
Used by client-side scripts to send data to and receive data from the ServiceNow server
Client-side script passes parameters to the Script Include, which returns data as XML or JSON object. The client-side script parses data from the response and can use the data in subsequent script logic
Service Catalog > Catalog Definition > Record Producers
How to navigate to Record Producer
A specific type of catalog item that allows end users to create task-based records, such as incident records, from the service catalog
task records, request item
Record producer is similar to that of a catalog item but generates _______________ instead of a ________________
Define the redirect link in the "Script" field:
___________ control access to features and capabilities in applications and modules
Access to modules in the Application Navigator is a controller by __________
Set of users who share a common purpose, may perform tasks such as approving change requests, resolving incidents, receiving email notifications, or performing work order tasks
Instead of individually assigning roles, assign a role to a ___________
Override application menu roles
This option gives module-level access to a role that is not authorized to see the application
Temporarily allows admin users to become another authenticated user for testing purposes
Restrict access to data by requiring users to pass a set of requirements, defines:
•What is being secured
•The operation being secured
•The permissions required to access the object
To be granted access by the _____________, a user must have the role specified for the table
All Access control operations (except read) require elevated security privileges
Table/field, Requires Role, Condition, Script
Four sections in Access Controls:
Access Control Execution plan
•Red text: An Access Control that was activated or deactivated
•Blue text: An Access Control that was modified
•Green test: An Access Control that is added or has become active
•Masked: An Access Control that was effective until you made a change
•Unmasked: An Access Control that was made effective when you made a change
Grant access to records and all fields in the records
Grant access to all fields where there is no field-specific Access Control
Best Practice: None and *
You cannot write * Access Controls without None because only None grants access to records.
When writing an ACL that mostly grants access, use only None.
When writing an ACL that mostly denies access, use None and *.
True//False An ACL can't have a NONE Access Control and a * Access Control
_____________in an Access Control specifies the table record to protect and a field to protect, the field list has a -None- option and a * option
System Security > Debugging > Debug Security Rules
To enable Access Control debugging, use Application Navigator in the main ServiceNow browser window
Access Debug color code
•Green: Access granted
•Red: Access denied
•Blue: Does not to be re-evaluated, already in cache
•Gray: Not evaluated, part of the rule has already denied access
•Check mark: Passed
Client-side GlideUser (g_user) API
Server-side GlideSystem (gs) API
canCreate(), canRead(), canWrite()
Server-side GlideElement API has methods to check whether a user's role allows them to access the associated GlideRecord(s):
Determines whether an application can access resources from another application, Application designers can configure:
-Availability of cross-scope tables in Studio
-Ability for cross-scope scripts to run on application resources
Runtime Access Tracking
Use to managed script access to resources from other applications, also known as cross-scope access
None, Tracking, Enforcing
Runtime Access Tracking settings:
No Authorization required for application scripts to access resources from other applications, no record in the cross-scope access table
Allows application scrips to access resources from other applications, record for the access is automatically inserted in the cross-scope access table with a Status of Allowed (default setting).
Allows application scripts to access resources from other applications only after an admin authorizes the access, automatically added to the cross-scope access table with Status value of Requested
Table, Script Include, Scriptable
Cross-scope privileges can be granted for:
Application Access Web Services
The Allow access to this table via web services option determines whether users can make inbound web services request to the table
Allows out-of-scope applications to create application files for tables:
