Hello Community - I have this date table I have imported from the team over at Enterprise DNA.
It's great, but I am realizing it is very specifically set up for ISO standards. Our company does not report using ISO. For example, our current week is Week 25. ISO is 24.
I was using this mcode before for the Week Number but now with this date table I cannot add it.
InsertWeekNumber= Table.AddColumn(InsertWeekEnding, "Week Number", each Date.WeekOfYear([Date],1)),
Ideally, I just want a "normal" calendar date table without the specifics of the ISO standards. Is there a way to modify this to achieve this?
