Revising variant items and generic modules

When you create a variant item, Teamcenter links it to the generic module item revision from which it is generated. This relationship allows you to search for variant items. It also prevents any changes to the variant items, unless they are unlinked. However, you cannot search for unlinked variant items. You cannot make changes to the option data, add or remove static components, or apply variant conditions to a generic item if it is linked to a variant item, as these actions would cause inconsistencies. You must revise the generic item before making changes.

Caution If any option data is changed on the newly-revised generic item, you cannot revise the existing variant items, but must create new variant items. At this point, there are no longer any variant items linked to the new generic item revision. The changes made are not reflected automatically in any existing variant items linked to previous generic item revisions. You must search for the affected variant items and update them individually with the changes. However, you cannot make structural changes to the generic item when it is linked to a variant item, including adding or removing a line, and creating a relation. You can change the item revision master form attributes on the variant item, but you cannot make structural changes. If you make changes to the master form attributes, you should search for other variant items that should be updated.
