Refering to a field , and manipulating that field in set analysis

[#1]

Hello,

I have two time fields, and want to use set analysis to set time1 >= (time2 minus 3 months). Is this possible? I have attempted this and have not had any luck. My attempt is below.

=count({$<Time1={"=Time1>=AddMonths(Time2,-3)"}>} Distinct OrderID)

Any help would be appreciated.

Thanks Much!

Hello,

try

=count({<Time1>=$(=AddMonths(...))>} distinct OrderID)

The trick is, to embrace the expression in $(). This makes QV to evaluate the expression.

hth,

Sorry ... too quick reply ... I checked my own code now ... I use it like this:

SUM( {<DateDMY={'>=$(=AddMonths(monthstart(max(DateDMY)),PeriodMonths)) <=$(=monthend(max(DateDMY)))'} >} Value)

First, thanks for the response.

However It seems that you only refer to one time field (DateDMY) in your expression.

I actually want to evaluate where DateDMY >= Date2DMY-3 months. So I have two separate date fields in total in the expression. Hopefully this makes sense

Regards.
