How to get the LTM (Last 12 months) rolling calculation
I am new to Qlik Sense. I need help regarding PRODUCT calculation in qliksense. My requirement is to get the Cumulative returns for the last 12 months for a particular selected entity.
As per the excel sheet below , i have to get the Cumulative value for Monthly Returns(net or gross). In order to get Cumulative value (Column H) for a "selected" EntityId 1, for Date 28th Oct 2018, i need the product of last 12 months of (Monthly Return +1) and -1 from it.
Formula in Cumulative LTM = PRODUCT(Monthly Return+1) for last 12 months) -1
I shall be having a dropdown to select the EntityId and Dates. Therefore, these are dynamically changing.
