What is the difference between difference network, network merge mode and version comparison?
The function known as 'difference network' is called 'network merge mode' since Visum 11.5, because its essential feature is merging networks.
Attribute comparisons between network variants have ever been the main use case of the difference network. Since Visum 11.5, such comparisons can be executed in a considerably more comfortable way by using the new version comparison. Differently to former difference networks, network editing, procedure execution etc. are nonrestrictively possible, even after version comparisons.
