Room is not available at the time of Event Creation

Dear All,

I have created these objects..

Resource (Room1)

Location (Campus1)

Resource Type (Lecture Hall)

I already associated Resource with Location and Resource Type.

Apart from it I have Linked Resource Type with Business Event Type.

But still when I am going to create an event for the event type I do not get any available room and building.

Even if I am choosing any default entry (already provided in IDES system), I am not getting room attached to locations.

I have done it in my earlier project, but now its missing.

what could be the reason? Please help.

Thanks in Advance.
