_______________object • 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

• Using the Script Editor to find JavaScript syntax errors • Examining scripts to look for errors • Verifying the trigger is configure correctly

Business Rule debugging before has been:

System logs, Debug Business Rules (Details), JavaScript Debugger

Business Rule debugging strategies:

Dot-Walking

Allows direct scripting access to fields and field values on related records

GlideSystem, GlideRecord, GlideDataTime

Commonly used server-side APIs

GlideRecord

________________ is a server-side API that: -is a special Java class that can be used in JavaScript exactly as if it was a native JavaScript class. -is used for database operations instead of writing SQL queries. -is an object that contains zero or more records from one table

JavaScript Debugger             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

Breakpoints

Pauses script execution to give developers the chance to examine variables and their values

Script Includes

Reusable server-side script logic that defines a function or class

Script Includes

____________________ execute their scripts logic only when explicitly called by other scripts

Self-Executing

__________________ 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

GlideAjax

Used by client-side scripts to send data to and receive data from the ServiceNow server

GlideAjax

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

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 ________________

producer.url_redirect, producer.portal_redirec t

Define the redirect link in the "Script" field:

Roles

___________ control access to features and capabilities in applications and modules

roles

Access to modules in the Application Navigator is a controller by __________

Group

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

Group

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

Impersonating Users

Temporarily allows admin users to become another authenticated user for testing purposes

Access Controls

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

Access Controls

To be granted access by the _____________, a user must have the role specified for the table

security_admin

All Access control operations (except read) require elevated security privileges

Table/field, Requires Role, Condition, Script

Four sections in Access Controls:

Access Control                     •Red text: An Access Control that was activated or                                      

Execution plan

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 untilyou made a change • Unmasked: An Access Control that was made effective when you made a change

-None-

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 *.

False

True//False An ACL can't have a NONE Access Control and a * Access Control

Name field

_____________in an Access Control specifies the table recordto 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	•Green: Access granted
code	•Red: Access denied
	•Blue: Does not to be re-evaluated, already in cache
	•Gray: Not evaluated, part of the rule has already denied

Server-side GlideElement API has methods to check whether a user's role allows them to access the associated GlideRecord(s):

Application Settings

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:

None

No Authorization required for application scripts to access resources from other applications, no record in the cross- scope access table

Tracking

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).

Enforcing                            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

Table, Script Include, Scriptable

Status value of Requested 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

Allow Configuration

Allows out-of-scope applications to create application files for tables: -Business Rules -Client scripts -New Fields -UI Actions

Workflow

A sequence of activities for automating processes in applications

Activities

_________________ are workflow blocks which perform different tasks; such as obtaining approvals, sending email, running scripts, testing conditions, and setting field values on records

Start, End

All workflows start with a _______ activity and end execution with an ______ activity

Triggered by field	Workflow are launched a number of different ways
values on a record, UI	including:
Action, Server-side
scripts

Document Feed

-Role Required: personalize_dictionary or admin -A live feed group that is associated with a record, such as an incident or change

Document Feed

-Is unlisted; it does not appear when users view all groups on live feed. -Automatically approves membership for every user who can access the record. -Uses the record number as the group name. -Uses the record short description as a group description. -Maintains all messages posted to live feed on the record, if the record has a journal field for comments. If the record has a standard text field for comments, each live post overwrites the field value. -Maintains all messages posted on the record in live feed if the record has a journal field for comments. When the group is created, existing messages are added to the document feed.

Application Properties

Configurable application parameters for changing an application's behavior

No

Can an application system property be a reference field?

GlideSystem getProperty()

Use Scoped ________________ method to retrieve Application Property values

Scheduled Script Execution

Automated, server-side script logic which executes at a specific time or on a recurring basis

Execute Now

To test a Scheduled Script Execution, use _____________________

Event

An indication in ServiceNow that something notable has occurred, can be generated by server-side scripts, workflows, ServiceNow processes, or by user actions

Add event to the EventRegistry, Generate the vent, Create logic to respond to the event

Generalized process for working with events is:

Event Registry

ServiceNow can only respond to events which are registered with the ______________

-Server-side script using the gs.eventQueue() method -Workflow Create Event activity

There are two ways to generate events:

Event Log

Checking for events that have been generate

Email Notification, Script Action

Two possible ways to respond to events

Record are inserted or updated, Events aregenerated, the Notification activity executes in a workflow

Notifications send outbound email to recipients, when:

outbound email

Notifications send _____________ to recipients

when to send, who will receive, what it will contain

Three sections to configure in a Notification:

-Email will go to expected receipients -The Subject field resoves correctly -The Message Body HTML field resolves correctly

Previewing notifications allows you to verify:

• current (GlideRecord API) • email (GlideEmailOutboundAPI) • template (TemplatePrinter API) • event (Only for notifications responding to events)

Script Field has access to:

Inbound Email

Mail sent from any user into ServiceNow

Inbound Email Actions

_________________enable you to define the actions an instance takes when receiving email.
