Try likethis

=sum({<Week = {'$(vmax)'}>}Sales)

where vmax = Max(week)

use below code

sum({<Year={$(=max(Year))},Week={$(=max({<Year={$(=Max(Year))}>}Week))}>}Sales)

it will calculate max week on the basis of Max Year

hope this helps

I have modified your script as

lOAD *, Year&Num(Week,'00') AS YearWeek Inline

[Year, Week, Sales

2012, 32, 434

2012, 33, 457

2012, 34, 480

2012, 35, 277

2012, 36, 251

2012, 37, 242

2012, 38, 243

2012, 39, 250

2012, 40, 228

2012, 41, 247

2012, 42, 239

2012, 43, 277

2012, 44, 298

2012, 45, 314

2012, 46, 349

2012, 47, 349

2012, 48, 358

2012, 49, 336

2012, 50, 321

2012, 51, 300

2012, 52, 306

2013, 1, 291

];

Then use expression as

If you have only one entry per week then use this

=FirstSortedValue({<YearWeek-={$(=Max(YearWeek))}>} Sales, -YearWeek)

If you have more than one entry per week the use this

=FirstSortedValue({<YearWeek-={$(=Max(YearWeek))}>}Aggr(Sum(Sales),YearWeek), -YearWeek)

Hope it helps
