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.

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.

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.

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.References:Transform Maps, Business Service Management Map, Data Sources, CI Relationship Builder
