About exporting and importing incremental change data

You can export changes (deltas) to the structure if they are tracked by incremental changes in two formats—TC XML using a briefcase file or PLM XML. Teamcenter allows you to export the structure changes alone (not the entire structure) without needing to create a new revision. The exported changes contain all the relevant data required by the importing site to achieve the same structure configuration as exists at the exporting site. You can export multiple independent, dependent, or overlapping incremental changes in a single action.

When you use this feature, you must ensure the structure is configured with the required effectivity and revision rules before initiating the export. Effectivity and revision rules are not exported with the changes; you must ensure they are identical in the exporting and importing sites separately.

Teamcenter tracks and exports the following changes when they are tracked by incremental changes:

• Adding a new or existing line to the structure

• Adding a new or existing subassembly to the structure

• Removing a line or subassembly from the structure

• Modifying relative occurrence properties

• Creating or modifying absolute occurrence properties

• Adding a new or existing attachment to a line, for example, a form or dataset

• Deleting an attachment

• Modifying an attachment

When exporting incremental change data using PLM XML:

• The structure must be fully configured.

• Any related changes that are not tracked by an incremental change are not considered for export.

• Changes in the context of incremental changes are considered as export candidates. For example, if you add, modify or remove a structure line in the context of an incremental change, all of its parents up to the top level are exported in addition to the affected line. However, the siblings of lines affected by the incremental changes are not exported.

• If you add, modify, or remove a subassembly under an incremental change, its children exported even though they are not directly affected under the incremental change.

You can create an incremental baseline for a structure that was already exported. This action creates a new revision of the structure. As active changes are carried forward into the new incremental change baseline revision, you may add new incremental change elements (ICEs) affecting the new structure revision to the incremental change revision that is the parent of the original active ICEs. (This incremental change revision may already be exported for the original structure.) Because the new ICEs do not affect the revision of the structure that was exported when you perform a TC XML export, they are exported as a stub. The incremental baseline action has no additional effect on the export of the original structure and the incremental change revisions that affect it.
