Selection in expression

[#1]

Hello,

I have this expression:

sum({$<SText={'G','I'},KGroup={'13'},InvoicePeriodCounter={"$(=(max(InvoicePeriodCounter)-12)) " },InvoiceYear=,InvoiceQuarter=,InvoiceMonth=,InvoiceYearMonth= >} deb_price

Though I have other entries in KGroup, about 20, I would like to do selection like this KGroup <>{'13'}.

Is there any conveniant way to do this ?

kindly

Håkan

KGroup -= {'13'}
