I need a result table something like this...

product	Contribution	Total	2012	2013	2014
Total	100%	150	35	45	70
mp3	30%	45	10	15	20
tv	43%	65	20	20	25
camera	27%	40	5	10	25

For individual years & totals, I am using these 4 expressions (with product as a dimension):

2014: Sum (if (fyear = currentyr, net_price_amt, 0))

2013: Sum (if (fyear = currentyr-1, net_price_amt, 0))

2012: Sum (if (fyear = currentyr-2, net_price_amt, 0))

All 3: Sum (if (fyear = currentyr, net_price_amt, 0))+Sum (if (fyear = currentyr-1, net_price_amt, 0))+Sum (if (fyear = currentyr-2, net_price_amt, 0))

For Totals (last 3 years only), I am using this expression below, but it is not working .

Aggr(Sum (if (fyear = currentyr, net_price_amt, 0))+Sum (if (fyear = currentyr-1, net_price_amt, 0))+Sum (if (fyear = currentyr-2, net_price_amt, 0)), pldesc) / Sum(TOTAL if (fyear = currentyr, net_price_amt, 0))+Sum (TOTAL if (fyear = currentyr-1, net_price_amt, 0))+Sum (TOTAL if (fyear = currentyr-2, net_price_amt, 0))

Please note, I have to eliminate 2011 data, hence the expression above.

What am I doing wrong?

Thanks in advance !

Please note, If I didn't have other fiscal years in my underlying data, I would just use this as the expression and it works fine:

Aggr(sum(net_price_amt),pldesc) / sum(TOTAL net_price_amt)
