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.

ServiceNow provides several methods to install applications onto an instance, each suited to different scenarios:

Import an Application from an XML File (Option A):

Description: Developers can export an application as an XML file and then import it into another ServiceNow instance.

Use Case: This method is commonly used for moving applications between instances, such as from development to production.

Procedure:

Navigate to "System Applications" > "Applications."

Click on the "Import" button.

Upload the XML file of the application.

Inherited fields in ServiceNow are fields that are part of a parent table and automatically become part of child tables through inheritance. This structure is foundational in the ServiceNow data model, ensuring that child tables maintain a consistent relationship with their parent tables.

Here’s why inherited fields cannot be deleted from a child table:

System Design:ServiceNow employs a table inheritance model where child tables derive fields and properties from parent tables. Deleting inherited fields from a child table would break the integrity of the data model, as those fields are shared across multiple tables.

Impact on Functionality:Many inherited fields, such as sys_created_on or sys_updated_by, are integral to the functionality of the platform. Removing them could disrupt workflows, reporting, and auditing capabilities.

Alternative Approach:If you want to hide or restrict access to inherited fields in a child table, you can use ACLs (Access Control Lists) to prevent users from viewing or modifying these fields. Another option is to use UI Policies or Client Scripts to control their visibility on forms.

Developer Note:Attempting to delete inherited fields violates ServiceNow’s core principles of maintaining a robust and unified data structure. The platform enforces these rules to ensure consistent behavior across all tables in the hierarchy.

The statements that must evaluate to true for a user to pass an Access Control are:

Conditions configured in the Access Control must evaluate to true.

The user has one of the roles specified in the Required roles related list.

Scripts configured in the Access Control must evaluate to true.

An Access Control is a rule that determines whether a user can access a particular object or operation in ServiceNow. An Access Control consists of three elements: Conditions, Roles, and Script. Each element specifies a requirement that the user must meet to access the object or operation. If any of these elements return false, the Access Control denies access and stops evaluating the remaining elements. Therefore, for a user to pass an Access Control, all three elements must evaluate to true.

The other statements are not required for a user to pass an Access Control. Other matching Access Controls for the records do not need to evaluate to true, as only one matching Access Control needs to return true for access to be granted. The user does not need to be granted access through a business rule, as business rules are not part of Access Controls and do not affect their evaluation.

In ServiceNow, the Caller Access field is used to define the level of access that external scripts or applications have to a particular script include or application resource. The valid options for the Caller Access field are:

None: No special restrictions are applied; the resource is accessible as defined by other security settings.

Caller Restriction: Limits access to the resource, allowing only specified callers or applications to invoke it.

Caller Tracking: Enables tracking of which callers are accessing the resource, providing an audit trail for monitoring purposes.

Options such as "Accessible from," "Allow Configuration," and "Caller Permission" are not valid selections for the Caller Access field.

For more detailed information, refer to the official ServiceNow documentation on Restricted Caller Access Privileges.

A module is the functionality within an application menu such as opening a page in the content frame or a separate tab or window. For example, Open is a module under the Problem application menu that opens a list of problem records. Modules are the second level navigation options for applications.

Search branch and merge branches are available features in Studio. Search branch allows you to search for a specific branch name or ID in your Git repository. Merge branches allows you to merge changes from one branch to another, resolving any conflicts that may arise. Push to external source control and push to update set are not available features in Studio. Push to external source control is a feature of Source Control Integration, which is a separate application from Studio. Push to update set is a feature of Update Set Previewer, which is also a separate application from Studio. Reference: Studio, Source Control Integration, Update Set Previewer

Application Files are ServiceNow artifacts comprising an application. An application is a group of files and data that work together to provide a service or functionality. An application file is a specific type of file that belongs to an application, such as a table, a script, a form, a business rule, a UI action, etc. Application files define the structure, logic, and interface of the application. An XML export of an application’s table records, XML exports of an application’s Update Set, and CSV files containing data imported into an application are not examples of application files, as they are data formats that can be used to transfer or store information related to an application, but not the application itself.
