Revision effectivity principles

Note As an alternative to revision-based effectivity, consider incremental change. You can use revision effectivity to control when various revisions of an item are in effect. The product structure can be configured for a particular date or unit (serial) number by the application of a revision rule. The following example shows an application of revision effectivity. When you set an effectivity range, consider the following: You express effectivity as a start to end range of dates or unit numbers, for example, 1–May-2007 to 31–May-2007. You can configure open-ended effectivity with an infinite end date or unit number (UP) or until stock is out (SO). For example, 1–May-2007 to UP or 1–May-2007 to SO. UP and SO are both provided to aid integration with ERP systems but, in Teamcenter, they are functionally the same. Effectivity may be discontinuous, for example, 1–May-2005 to 31–May-2007, 1–July-2007 to UP. Effectivity can be shared. A reusable effectivity has an identifier. You must qualify unit effectivity by an end item, for example, Unit 10 to UP, End Item A1000.
