Comparing data by week and the same week number from a previous year.
Hi DLimerick
"Calculation error in measure. a date column cntaining duplicate dates was specified in the call to function'SAMEPERIODLASTYEAR'. This is not supported."
The date column in your dataset contains duplicate values, for example, there are two rows of 2018/1/2, right?

Hi,
I'd like to restart this thread as I have this exact issue. We would have multiple dates in the source data. However, our periods are 4/4/5 and would like to compare prior week, prior year week, and prior year YTD (by week).
Would this be possible?
TIA,
Stuart

Will do, however the original post hadn't been solved, so I thought other people who have the same issue wouldn't want to trawl through numerous posts to get an answer.
