Using baselines

During the development of a product design, you may want to share your working design with other users. You may also want to save an interim version of your design for future reference. To do this, you can create a baseline of the work-in-progress (WIP) design. When you request a baseline, Teamcenter creates a new revision for each unreleased revision in the structure and releases it with a predefined status, for example, TC_Baseline. It also links the new revision with the WIP revision using an IMAN_baseline relation. This method configures a completely released structure and thereby guarantees that the models are the same as when the baseline was created. When you create a baseline, Teamcenter observes deep copy rules when copying datasets, forms, and other attachments associated with the item revision. Siemens Digital Industries Software recommends you use CopyAsObject in deep copy rules as the baseline process takes a snapshot of objects in their current state. If the baseline finds an invalid item type or the current user does not have write access to any of the items, the baseline operation is rolled back. Before creating a baseline, Siemens Digital Industries Software recommends you first perform a dry run mode to identify invalid conditions. The baseline process always starts from the top line of the current window, regardless of the selected line. The baseline operation processes lines that are configured out by variants or occurrence effectivity. Substitutes and packed lines are always processed. However, if the structure has suppressed components, you can optionally process them by selecting Show Suppressed Occurrences. If the structure has incremental changes, Siemens Digital Industries Software recommends you use incremental change baselines. To view the completed baseline, load it into Structure Manager after applying the appropriate revision rule. You can set the Baseline_precise_bvr user preference, which controls whether a precise or imprecise baseline is created. If the latest revision is the baseline revision, Teamcenter generates the next revision ID based on the ID of the revision of the baseline revision. You can also create a baseline of a single item revision in My Teamcenter. In this case, a new copy of each BVR of the WIP revision is created. The precision of the new BVR is the same as that of original BVR, irrespective of the setting of the Baseline_precise_bvr user preference.
