ServiceNow Things to Know 33: Dictionary Attributes

PrashantLearnIT · ‎12-18-2023

Did you know that ServiceNow offers many Dictionary Attributes to modify the behaviour of a table or a field?

To administer Dictionary Attributes for a Table or a field simply navigate to:

System Definition > Dictionary > Dictionary Entry and add the required attribute to the Attributed field (under the Advanced View) or by using the Attributes related list.

Alternatively directly form a record you can use the context menu to configure the dictionary for the table or directly on a field to configure the attributes for a single field.

Note: Attributes are comma-separated; if attributes exist on a dictionary record, add a comma, with no spaces, before adding an attribute (when not using the related list).

Note: If you remove an attribute that is part of the base system, it is automatically restored during an upgrade. To prevent upgrades from changing the desired behavior of your system, leave the attribute on the table or field, but set its value as desired.
