Deliver changes from the foundation in addition to changes from the stream
This policy applies to intraproject deliver operations. There is another version of this policy for interproject deliver operations.
For intraproject and cross-project (interproject) deliveries, this policy specifies whether the target stream allows deliveries from source streams that include changes not from their foundation baselines; that is, whether the source stream is allowed to deliver only changes made within the source stream.
If you set this policy to enabled, the target stream accepts changes in the source stream that result from differences in the foundation baselines of the two streams in addition to the changes in the source stream that the developer makes while working on assigned activities.
