When messages in project data are reported in the Notifications panel, the Description field typically indicates an action should be taken to resolve the message: “Value should be specified”. An unresolved message can result in incomplete calculation or simulation results, but is generally not severe.

Double clicking on the message opens the Properties dialog populated with properties of the Project Tree item listed in the Notifications panel Object column, and selects but does not highlight the property listed in the Notifications panel Field column.

You can set the value to resolve the notification message.
