Storing variant data

Variant data can be stored on the following objects: Item revision: Options and allowed values Fixed and derived default values Variant rule checks Occurrence: Variant conditions Controlling changes Changes to variant data can have a dramatic effect on variant configuration. You can control changes with techniques such as access control lists (ACLs), locking, and release procedures. Any user can set the variant rule to configure a particular variant. Users creating variant data must ensure that the necessary variant rule checks exist so that only valid rules can be set. You can use menu entry suppression to hide the variant rule entry from certain users and groups. Variant data is owned by a specific revision of an item. As the item evolves, it may be necessary to change the set of allowed values for a particular option or possibly to add further options. Existing values must not be referenced anywhere in the structure or you cannot remove or replace them.
