Hellou!

At this point I'm trying to model water distribution network with Mike Urban. I have tried to create two scenarios to the model: One for the present and on for the future.  With those two scenarios I'd like to perform the calculations with different water demand data.

In the scenario manager i have created own demand alternatives for the both scenarios and selected them for the scenarios. However when i change demand data in scenario 1 the change transfers also to the scenario 2. Could anyone help me with this problem? What could be wrong with my scenarios? How can I get own demand data for the scenarios?

Also, when I change the scenario in the scenario manager i get following error message: "There are errors in geodatabase which can cause unpredictible behaviour of ScenarioManager, or maybe data-loss. Please use Project Check Tool to correct these errors: Value in unique column(s) cannot be NULL: table=mw_MDemand, column1=JunctionID, column2=Sqn". What does this mean?
