Previous year comparison

[Newbie777]

Hello,

I am new to Qlik Sense, and I am looking for a similar function with Sameperiodlastyear in DAX (Power BI's formula language).  I'd appreciate it if you could let me know how I can tweak the expression below to achieve the similar effect as sameperiodlastyear function in DAX.  

Sum({$<[Date-Posting Date.autoCalendar.Year] = {$(=Year(Today())-1)}>}[Expense])

Thank you for your help!
