These values can be found. However, they won't be able to be placed in the desired place on a worksheet. Each value can be found on separate sheets and then placed on a dashboard together in the desired view.
To get #1, create a calculated field similar to the following:
(ZN(SUM([TrxCount])) - LOOKUP(ZN(SUM([TrxCount])), -1))
To get #2, the calculation should look like the following:
(ZN(SUM([TrxCount])) - LOOKUP(ZN(SUM([TrxCount])), -1)) / ABS(LOOKUP(ZN(SUM([TrxCount])), -1))
Hope this helps!
This calculation is very helpful. Thanks for passing along.
I added the calculation and changed [Calculation1] to [Compute Using: Advanced], [Addressing: Year of Date]. This gave me YOY growth numbers I was trying to compute.
I then added [Calculation1] to the Measure Values, but of course I wanted to see it as a 'column' not a row:
So I then grabbed on the row box icon:
and dragged the icon up to the column:
This gave me nearly the result I was looking for, with the only exception being that 2012 shows up on the display & is 'blank'
Would it be possible to write additional syntax in the formula to isolate / hide the blank 2012 values (above in red)? If so, I would call this close enough for the report I'm trying to produce.
Thanks again for any insight!

Figured it out. Needed multiple calculated fields:
[1Q12] = IIF(YEAR([Date]) = 2012, IIF(MONTH([Date]) < 4, [TrxCount], 0), 0)
[1Q13] = IIF(YEAR([Date]) = 2013, IIF(MONTH([Date]) < 4, [TrxCount], 0), 0)
[B(W) #] = SUM([1Q13]) - SUM([1Q12])
[B(W) %] = IIF(SUM([1Q12]) = 0, 1, (SUM([1Q13]) - SUM([1Q12]))/SUM([1Q12]))
Piece of cake actually.
Example workbook attached. Hopefully this helps someone else that was looking for this information!
