Branch copy is a very powerful action, widely used in what-if-scenario analysis.
It can also be used to copy, for example, promotion events.
The problem is, when we create a copy of a completed promotion event also the status is copied indicating that the newly copied event is also completed, which obviously is not the case.
The idea is to add a list of exceptions to copy branch functionality (to exclude specific line items from being part of the copy, while using copy branch). As a result Status of the copied promotion event can be BLANK, or defaulted through this exception rule, example given: Planned.
