One reason Why I am applying is dynamic ageing when user select back date ie suppose as off '31-12-2013' status while taking report then this report should generate from qlikview , So I pulled all open documents as well as there collections (payments along with ) for eg following data
Inv 1031 amt 2000 dated 31/4/2013 Bal 500
paym 1242 amt 1500 Date 1/5/2013
So Balance 500 I am calculating through AGGR function. Now I need to calculate as per dynamic bucket how to show any IDEA.
