About Canceling Integration Changes
You can cancel the integration process in one of the following ways:
Click Cancel in the Integrate window.
Click Close in the Integrate window.
Close or replace either the base model or the comparison model.
Undo checkout.
After canceling the integration process, the iteration of the object in the workspace changes, but the changes are not integrated.
If the integration operation is not completed, or if it terminates abruptly, Windchill treats the termination as a normal cancellation. However, you can use the updated model from your workspace to restart the integration process.
