I have a chart with a calculated date dimension. One of the issues I had in the past with original versions PowerPivot was that there was only 1 possible sort order based on display.
So what happens when Apr comes before Jan in a textual sort in Qlikview?
This calculated dimension expression takes advantage of the dual function to represent dates as numeric for sorting purposes:
=dual(month(MaturityDate) & '-' & Year(MaturityDate),Num(year(MaturityDate),'0000') & num(Month(MaturityDate),'00'))
By sorting numeric, this expression will show the proper sort order for dates.
Helping threads here.
