Period Comparison is always an issue,today I have to compare Week 2014/22 with week 2013/22.Something like using SET for my vLastYearWeek=WeekName(vPriorYearDate).
To Show up in a Tab Diagr for easy reference :-)
Any idea? thanks in advance!
This qlik demo does something similar with quarters that may be able to provide some insight for you
