Working with cumulative for Pareto

[#1]

My data is has following cols

Country, State, Period(in mm/dd/yyyy format), Qty, Year

A, A1, 1/1/2015, 10, 2015

A, A2, 1/1/2015, 20, 2015

A, A1, 2/1/2015, 25, 2015

A, A1, 1/1/2014, 15, 2014

A, A1, 2/1/2014, 10, 2014

B, B1, 3/1/2015, 30, 2015

I want to achieve the following output

Year     Country     Sum(Qty) (for the Year) (in descending order)     Cum Qty          Cumulative % (at  Year level)

2015                   A           10+20+25=55                                          55                  =55/(55+30)

2015                   B            30                                                         55+30=85        =85/(55+30)

2014                   A            15+10=25                                               25                 =25/(25)

Any help much appreciated.

Currently I achieve the above checking the Relative and Full Accumulation options.

Here is a different approach.

Create a straight table with dimensions Year and Country and first Expression

=Sum(Qty)

Sort your table first by Year desc, then by Sum(Qty) desc.

Add two  expressions:

=rangesum(above(sum(Qty),0,rowno()))

=column(2) / Sum(Total<Year> Qty)
