Qlik Sense How to get previous filter value

[Peter_QS]

Hi,

I have a date filter like 'January 2019' and I would like to access to the previous value of the selection ('December 2018' in this case) to present two KPIs . Is there a way to do it ?

Thanks

You can use the previous set identifier

If, for example, your original expression was Sum(Sales), your previous selection expression would be Sum({$1} Sales)
