Appendix B - Attributes IDs for customizing the luggage tag
You can use the ConfigKeyFormat option to customize the luggage tag for displaying one or more custom attribute fields (refer to Customizing application settings).
For example, you may want to configure the luggage tag to display only the Matter Number, or to show the Client, Engagement, and Year fields. The following table provides a mapping of custom attributes to their IDs, which need to be used while setting the value for the ConfigKeyFormat option.
