Hi everybody,
I�m addressing this question mostly to those of you who already finished (and passed!) the part 2 of the SCEA exam in an attempt to clarify myself about an aspect of the SCEA assignment (old one � FBN).

I�m mostly confused about the Prepare Itinerary in conjunction with Change Itinerary.
-Change itinerary will allow the customer to remove only one segment , thus, if the entire itinerary is formed of 3 segments, only 2 of them will remain in the itinerary. Then we are redirected to the Prepare Itinerary.
-Prepare itinerary, on the other hand, asks the customer again for the departure city/date and the arrival city/date and, after a few steps, it comes up with a NEW itinerary.

Can somebody clarify this aspect, please ?

You can make an assumption that if the other module came from the other then it should behave differently than starting from scratch.

Just make sure that all important assumptions you made are mentioned in your submission.

Just mentioning that the use case (sequence diagram) is supposed to behave differently when coming from the Change Itinerary should be enough ? Do I need to show this in the sequence diagram itself ?

Thank you.
