Creating an incremental change baseline

You should periodically create a new baseline revision for an item that is tracked by incremental change after a certain number of incremental changes are created. By default, all outstanding incremental changes are rolled into the new revision. This approach reduces the amount of data in the new revision and reduces the time needed to configure the assembly. Review the example of how incremental change baseline may affect the revision rules applied. When you create an incremental change baseline, the new revision of the parent assembly has the occurrences and attachments configured by the revision rule or unit effectivity set when you created the incremental change baseline. When you create an incremental change baseline, by default any active incremental changes are not carried forward to the baseline, as described later. However, you can optionally configure your system to roll up or carry forward active incremental changes. (Active changes are any changes that are currently effective or will be effective in the future.) Do not simply revise a structure that has incremental changes on any of the components because the incremental changes are not copied and the structure is not configured as expected. You must create the incremental change baseline first. Ensure the baseline cannot be modified by applying a status to apply vaulting to the BOM view revision, rather than the item revision. Do not use the status on the item revision for this purpose because the status is also used for configuration. You must have access to the incremental changes to create an incremental change baseline. If Teamcenter determines that you do not have the necessary access, it rolls back the baseline operation and does not create the new item revision.

Note Do not confuse incremental change baselines with creating standard baselines of item revisions. With standard baselines, if the item is an assembly, you can automatically create a new revision of any unreleased components throughout the substructure. With incremental change, the baseline is applied only to the product structure, not to the components. It is good practice to apply unit number effectivity to the assembly item revisions, even if the components are configured by incremental change. This approach identifies the effectivity of the new incremental change baseline revision, and also configure it appropriately. There should be no incremental changes on components in the new incremental change baseline revision that are effective prior to the unit number at which the incremental change baseline revision was created.
