Policies and rules properties in Table Builder

You can configure the basic field policies and rules for any field that you work with in Table Builder.

UI Policies

The UI Policies section enables you to configure how forms appear based on roles and user input.

To understand the basic field properties, see Create a UI policy in Table Builder.

The following table shows the field descriptions for the Policy details section when adding or editing a UI policy.

Field	Description
Short description	Short summary of the UI policy.
Table	Data table that the policy applies to.
Domain	Domain that the choice resides in.
Order	Sequence for processing, from the lowest number to the highest number. If two policies conflict, the UI policy with the higher number runs. For inherited UI policies, the extended \(child\) table's UI policies run first. Then, the base table UI policies run, both from the lowest to the highest specified value.
Active	Status of the UI policy. Only active UI policies are applied.
Apply to all views/Apply to view \[Advanced settings\]	Option for specifying whether the UI policy applies to all form views or specific views. For more information on form views, see View management.
On load \[Advanced settings\]	Option for specifying that the UI policy behavior should be performed OnLoad as well as when the form changes. Check or clear the UI policy On load check box to control whether it runs every time a form is loaded and conditions are satisfied. In the following example, an administrator does not want an incident to enter the Awaiting user info state unless the user provides an explanation to the customer. The administrator creates a UI policy with the following settings: In the When these conditions are met section, adds the condition [State] [is] [Awaiting user info] and clears the On load check box. The UI policy applies only when the state is changed to Awaiting user info. In the UI Policy Actions list, creates a record that makes the Additional comments field required when the condition is met.
Reverse if false \[Advanced settings\]	Option for specifying that the UI policy action should be reversed when the conditions of its UI policy evaluate to false. When the conditions are true, actions are taken and when they change back to false, the actions are reversed \(undone\).
Inherit \[Advanced settings\]	Option for specifying whether extended tables inherit this UI policy. When a child table has an inherited UI policy from its parent table, the UI policy on the child table always runs first, regardless of the Order of the UI policies. In the following example: A child table has a UI policy with theOrder value 500 that shows the Urgency field when its conditions are met. Its parent table has a UI policy with the same conditions that hides the Urgency field. The parent table UI policy has the Order value 100. Although the parent table Order field has a lower value, the child UI policy runs first and then the parent UI policy runs. When the conditions are met, the Urgency field is hidden.

The following table shows field descriptions for the When these conditions are met section when adding or editing a UI policy.

Field	Description
Condition set	Conditions that, if fulfilled, cause the UI policy to be applied. Conditions are built with the condition builder by using logic statements. To set conditions using a script, use a client script instead. Conditions are only rechecked if a user manually changes a field on a form. If the change is made by a UI action, context menu action, or through the list editor, it is not evaluated.

The following table shows field descriptions for the Do the following section when adding or editing a UI policy.

Field	Description
Field name	Field on the selected table to which the UI policy performs an action if conditions are met. Note: If the specified field is not on the form, the UI policy performs the action on the variable with the same name.
Mandatory	List for specifying how the UI policy affects the required state of the field. The choices are the following: Leave alone True False
Visible	List for specifying how the UI policy affects the visible state of the field, that is, whether it appears. The choices are the following: Leave alone True False
Read only	List for specifying how the UI policy affects the read-only state of the field. The choices are the following: Leave alone True False
Clear the field value	Option to clear the specified field if the conditions are met.

Access control rules

The Access control rules section enables you to configure access to the specified resource based on role, condition, and script criteria being met.

The following table shows field descriptions for the Access control rules section.

Field	Description
Name	Names each user who has permission to access the form or data. - Enter the names as firstname.lastname in lower case letters, separated by a period (for example, `john.smith`). Each name must have a corresponding user record in hi.servicenow.com. - Enter multiple names and separate them by commas if multiple users have permission to access the form or data. - Enter an asterisk (*) as the name to enable all users to access the form or data.
Description	Overview of what the access control rule restricts or enables.
Type	Type of object the access controls, including the following:- Client-callable script includes - Processor - Record - UI page - UX route For more information on object types, see ACL matching requirements for objects.
Operation	Type of action the system can take on the specified object, such as delete or execute. Some objects, such as records, support multiple operations, while other objects, such as a REST\_Endpoint, only support one operation. For more information on action types, see ACL rule types.
Active	Active state of the rule:- true The rule is active and available for use. false The rule is inactive and unavailable for use.
Condition	Any conditions that apply to the rule.
Roles	Any roles the rule applies to.
Admin overrides	Option to force the rule's evaluation for admin overrides at the access level. For more information on admin overrides, see Evaluate the admin override at the access level.
Advanced	Option to associate a script with the rule.

Client Scripts

The Client Scripts rules section enables you to create scripts that control how form fields appear based on defined criteria.

For a complete list of values for client script fields, see Client script form

The following table shows field descriptions for the Client Scripts rules section.

Field	Description
Name	Name for the script.
Description	Overview the script's functionality and purpose.
Table	Table or form that the script is available for.
Active	Active state of the script:- true The script is active and available for use. false The rule is inactive and unavailable for use.
UI type	Type of application the script is available for, such as desktop or mobile.
Type	When the script runs on the table or form, including the following:- onCellEdit - onChange - onLoad - onSubmit
Field name	Field the script is run on.
View	Views on which the client script runs \(not applicable to global scripts\).
Inherited	Indicates whether the client script applies to extended tables.

Business Rules

The Business Rules section enables you to create business rules to accomplish tasks like automatically changing values in form fields when certain conditions are met.

For a complete list of values for business rules, see Create a business rule.

The following table shows field descriptions for the Business Rules rules section.

Field	Description
Name	Name for the business rule.
Table	Table or form that the business rule runs on.
Active	Active state of the business rule:- true The business rule is active and available for use. false The business rule is inactive and unavailable for use.
When	When the business rule executes: display, before, async, or after the database operation is complete.
Filter conditions	Conditions created using the condition builder to determine when the business rule should run based on the field values in the selected table.
Role conditions	Roles that users who are modifying records in the table or form must have for the business rule to run.
Actions	Actions taken by the business rule on the specified fields, such as insert, update, and delete.
Set field values	Table or form fields that the action executes on.
Add message	Whether a message appears when this business rule is run:- true A message appears when the business rule is run. false No message appears when the business rule is run.
Abort action	Whether the business rule aborts the current database transaction:- true The business rule aborts the current database transaction when run. false The business rule doesn't abort the current database transaction when run. For example, on a before insert business rule, if the conditions are met, do not insert the record into the database.
Order	Indicates the sequence in which this business rule should run. If there are multiple rules on a particular activity, the rules run in the specified order specified, from lowest to highest.
