Where-Used list for BEx query chars & KFs

Hello everyone. I am trying to find a way to identify what Characteristics and Key Figures are used withing an infocube in BW. I think that the BW Statistics cubes may help, but that was going to be my fallback option.

I couldn't find a way to do a where-used list for characteristic and key figures when in the Query Designer. I can do a where-used on restricted key figures and char. variables.

Does anyone know of other ways to do this. How about looking in some of the core BW DB Tables (eg. RS*)?

Thanks,

Kevin
