aggr working on version 11 but not 12

[Anonymous]

Hi guys

The following is working perfectly in version 11, but not 12. Please help.

The expression is:

=min(aggr({<AsOfDate={'>=$(vMinDate)<=$(vMaxDate)'},FromDate={'>=$(vMinDate)<=$(vMaxDate)'}>} exp(sum(log(1+Return)))-1,PortfolioName,FromDate,AsOfDate))

The variables are defined below:

vMinDate: Max(TOTAL aggr(Min(ReturnDate),PortfolioName))

vMaxDate: Min(TOTAL aggr(Max(ReturnDate),PortfolioName))

Thanks.

Joao

Are you sure this works in QV11.2? Because it looks syntactically incorrect - AFAIK Aggr() does not support set expressions directly, they need to be in an aggregation function such as Min(), Sum(), Avg()....

I see what you mean, and it certainly underlines many parts of the expression for this reason (suggesting there is a problem), but it has always worked. I've upgraded a couple of installations to version 12, and on these it is not working. The rest are still on 11.2, and it works perfectly (no changes i.e. we are all using the same models).

And I've tried changing the expression so that it is syntactically correct with the exp(sum( straight after the aggr( so that the set analysis happens inside the sum, but it still doesn't work. The new expression is:

=min(aggr(exp(sum({<AsOfDate={'>=$(vMinDate)<=$(vMaxDate)'},FromDate={'>=$(vMinDate)<=$(vMaxDate)'}>} log(1+Return)))-1,PortfolioName,FromDate,AsOfDate))

I've just removed the set analysis part out of the expression, and this works perfectly i.e. the expression is now:

=min(aggr(exp(sum(log(1+Return)))-1,PortfolioName,FromDate,AsOfDate))

I feel like variables work differently in version 12+ and Qlik Sense than they do in previous versions...
