Configuring a 120% BOM

A 120% BOM allows users to select multiple values for an option. Teamcenter evaluates the multiple values as an OR expression. For example: Copy Option: Color Valid values: Green, Yellow, Red If the user selects all the valid values to configure the BOM, Teamcenter evaluates the values as: Copy Color=Green OR Color=Yellow OR Color=Red In 120% BOM, defaults, derived default values and variant rule checks are not evaluated. When you load the BOM, Teamcenter does not change the active BOM mode unless you choose Allow multiple option values for option. In this case, it changes the mode to Single Rule-Multiple Values (generally called 120% BOM); otherwise, the selected variant rule is loaded in the default mode, that is, Single Rule-Single Value (generally called 100% BOM). You can change from a 100% BOM to a 120% BOM configuration at any time. When you change the mode from 100% to 120% and defaults or derived defaults exist, Teamcenter displays a message to ask if you want to carry over the defaults or derived default values as user set values in 120% mode. If you click Yes, Teamcenter carries these values over in 120% mode. If you click No, Teamcenter clears these values. Any modifications to the values while in 120% BOM configuration do not cause Teamcenter to evaluate default checks, derived default checks, or rule checks. Option values can only be set by a user, set by a rule, or unset.
