I am having problems with week based grouping.
All of the weeks are out by 1 week.
Week 1 is null and the data on week 2 is really the data from week 2.
For example records 05/01/2017 is are showing up in week 2 instead of week 1.
Has anyone else had this problem?
I am using Tableau online 9.3
I'm seeing something a little different (note I am in the US with a Sunday - Saturday week
2017 aligns like I would expect
2016 on the other hand has 2 day in week 1 and week 2 starts on the the 3rd
So it looks like Week 1 starts on Jan 1 and runs to the week end - that may not align with your business calendar
