Adding different KPI's to Time Hierarchy

Hi,

I've a 'Time.by week' Hierarchy as  - Year->week->Date .

I also have Sales budgets given to me for them.

let's assume the Sales budgets are as follows.

Yearly       Weekly       Daily

500000      9615      1373

I need to define the "Goal", "Status" and "Trend" KPI's and it should work across the levels of my "Time.by week" hierarchy.

I've built a simple KPI involving just the "Year" and it worked but I'm having difficulty when it involves a hierarchy like this one.

Any help would be appreciated.
