A UI Action is a button, link, or choice that can be clicked by a user to perform an action, such as submitting a form or running a script. The following are UI Action types:

List choice. This is a UI Action that appears as a choice list on a list of records. It can be used to perform an action on multiple records at once, such as deleting or updating them.

Form button. This is a UI Action that appears as a button on a form. It can be used to perform an action on the current record, such as saving or approving it.

List banner button. This is a UI Action that appears as a button on the banner of a list of records. It can be used to perform an action on the entire list, such as exporting or printing it.

The following is not a UI Action type:

Form choice. This is not a UI Action type, but a field type. A form choice is a field that displays a choice list on a form. It can be used to select a value from a predefined set of options, such as priority or state.Reference:UI Actions, Field Types

The source control operation used to store local changes on an instance for later application is called a stash. A stash is a temporary storage area for uncommitted changes that are not ready to be pushed to a remote repository. Developers can use stashes to save their work in progress without committing it to the local repository or discarding it. Stashes can be applied later to restore the changes to the working directory, or dropped if they are no longer needed. Reference: [ServiceNow Docs - Stash local changes], [ServiceNow Docs - Source control]

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.

The following platform feature can be used to determine the relationships between fields in an Import Set table to fields in an existing ServiceNow table:

Transform Map. This is a feature that defines the mapping between the fields of an Import Set table and the fields of a target table, such as incident, problem, or user. A transform map also specifies the logic and rules for transforming the imported data, such as coalescing, scripting, or applying data policies.

The following platform features are not used to determine the relationships between fields in an Import Set table to fields in an existing ServiceNow table:

Business Service Management Map. This is a feature that provides a graphical representation of the configuration items (CIs) and their relationships in the Configuration Management Database (CMDB). A Business Service Management Map can be used to visualize the impact of incidents, changes, or problems on the CIs and the services they support.

Data Sources. This is a feature that defines the connection and authentication information for an external data source, such as a file, a JDBC database, or a web service. A data source is used to import data from the external source into an Import Set table.

CI Relationship Builder. This is a feature that creates relationships between CIs in the CMDB based on predefined or custom rules. A CI Relationship Builder can be used to populate the CMDB with the dependencies and connections between the CIs.Reference:Transform Maps, Business Service Management Map, Data Sources, CI Relationship Builder

The following are debugging strategies for client-side scripts, which run in the web browser and manipulate the user interface:

g_form.addInfoMessage(). This is a client-side API that displays an information message at the top of the form.

Field Watcher. This is a debugging tool that displays the current and previous values of one or more fields on a form.

jslog(). This is a client-side API that writes a message to the browser console.

The following is not a debugging strategy for client-side scripts, but for server-side scripts, which run on the ServiceNow platform and manipulate the database:

gs.log(). This is a server-side API that writes a message to the system log.Reference:Client-Side Scripting APIs, Debugging Client Scripts

The application name is not required to link a ServiceNow application to a Git repository. You only need to provide the URL, user name, and password of the Git repository, as well as the branch name and the authentication type. The application name is automatically generated based on the scope name of your application. Reference: [Link an application to a Git repository]
