Convert YYMM into proper date
Hi, Anonymous ;
You colud use 3 methods to solve it , As Community Champion said, first in power query , another is create a column ,last create a measure. and the error you mentioned is because the measure you created is less than max or min. here are three ways：
Method1: add a custom column in power query.
#date( Number.FromText("20" & Text.Start([YYMM], 2)), Number.FromText(Text.End([YYMM], 2)), 01)Method2:Create a column in powerbi
date = DATE("20"&LEFT([YYMM],2),RIGHT([YYMM],2),1)
Method3:Create a Measure in powerbi.Measure = DATE("20"&LEFT(MAX([YYMM]),2),RIGHT(MAX([YYMM]),2),1)Best Regards,

Ok, so i found 'new measure' which allows me to add a Dax expression which seems to match the syntax of this reply. (couldnt get the power query answer working)
I receive the following error though:
"A single value for column 'ssYYMM' in table 'Query1' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result."
