Rooms overlap

[sdmaino]

First of all thank you for this tool.
I have a very simple plan (for test purposes, before making it complex)
I need to make a plan for a sport team, I have some trainers, some kids,two sports rooms.
In the very basic setup I made, FET freely overlaps teams in the same room, without even considering the second room I have
I surely miss something
Please can anybody have a look at the attached FET file...thanks.

Uhm, I made further tests.
I made both rooms completely unavailable but FET makes the plan without problems   
I definitely did not understand.
Thanks.

You need to add space constraints (preferred room(s) and/or home room(s)).

Thank you , I did not understand this; I supposed that without placing space costraints FET chose freely the room wothout any preference (which is what I really want).
So I suppose that to do it I can set constraints with 50% if I have 2 rooms, 33% if I have 3 rooms, etc.
Thank you.

No. You need to add an activity tag, say AT, for each activity, then constraint activity tag preferred rooms, 100%, all the rooms. Or use other constraints like this, 100%, all the rooms.
