Setting variant rules

You set the appropriate variant rule to obtain the required values for applicable options. You do not have to specify a value for every option and some options may remain unset; typically, you would set all options to completely configure a variant structure. Some options may appear already set because they have a default value that Teamcenter automatically sets. Structure Manager shows the item to which the specified default is attached. If you specify a derived default on an item, Teamcenter sets the default value once you enter a value for the primary option from which the default value is derived. Derived defaults are marked as potentially derived and, where possible, you should specify these values last. If you specify an option value that is disallowed by a variant rule check, Teamcenter displays an error message that states the problem and the applicable variant rule. Teamcenter only sets default values if the item to which the default is attached is loaded.
