Set Analisys with expression DSE

[#1]

Hi,

I'm a newbie in qlikview, so I'm readig some techincal manual to learn this environment.

Sorry if my question is already answered.

I have some problem with variables and expression.

In my application I have an expression defined as

eMaxAnnoSelezione = (Max(Anno))

where Anno is a field of my table.

so when I create a pivot table containing a sum on set analisys based on eMaxAnnoSelezione I'm unable to appropriate evaluate it (see the image).

Label works fine (caption become 'Totale ' followed by expression evaluation) but the expression doesn'w work.

I tried all possible combinations of DSE syntax... where I'm wrong?

thanks for your help.

$(eMaxAnnoSelezione) expands to a formula, so your set analysis is effectively this:

{$<Anno={(Max(Anno))}>}

This is not valid and will fail. On the other hand, it's perfectly valid in the label, because

='Totale' & (Max(Anno))

is a valid expression.

What you want to do, is probably to calculate the max year directly in the expression. To do that, define the variable as

=Max(Anno)

(the equal sign in front is key)

That way, it will evaluate to the max year for the current selection right in the variable itself, and then $(eMaxAnnoSelezione) will expand to the year value (2014 for example):

{$<Anno={2014}>}

which is valid and will work.

great, thanks.
