There's no capacity data to view for the selected hierarchy

[Satish Prabhu]

In the "Plan" View, when i chose the "capacity" on my "show timeline", i get the error shown in the subject. To build this plan, i used a board by name say "Board1". And i created another plan using "Board2" from the same project. ANd there i see the capacity of the team well. Can someone tell me what am I missing ? How is the board connected to capacity?
