Using item revision configuration

You can create and apply revision rules to select the appropriate revision of components in the product structure. A revision rule sets the criteria for selecting the revision, for example, whether to load working revisions or determining the released revisions that are loaded. This allows you to configure a structure as it was or will be on a particular date, for example, by utilizing effectivity data on each item revision (release status). Users can use combinations of effectivity data to do the following: Create and set date and optional end item revision effectivity. Create and set unit number and end item revision effectivity. Share an existing effectivity between structures. Create and share a named effectivity. Protect an effectivity so that only certain users can apply it. Both unit number and date ranges can be closed or open-ended. For open-ended ranges, UP and SO (stock out) values can be specified. Ranges can be discontinuous, for example, unit numbers 1, 5, 10–UP. A privileged user (typically, the system administrator) creates the revision rules that are then made available to other users. Consequently, nontechnical users do not have to understand the full complexity of revision configuration but simply apply the appropriate revision rule. Before creating or implementing item revision configuration, you must first implement the appropriate effectivity and release schemes.
