Plant Vs.Activity Types

Hi,

Where we can see the relationship Plant and Activity Types. I checked in KL03 but not able to see plant. I have plant "X" and plant "Y" and I have many activity types. But some activity types belongs to X and some belongs to Y. I need to update price in

KP26 for activity types and cost ceters for both the plants. ideally I have updated price for some cost centers and some activity types.. I want check those activity types belongs to Plant X or Y?

Thanks

Srinivas
