Hi,
Goal: I'm tryign to sort the column 'generation' by the column 'TotalSalesImpact' and I'm seeing the below error message suggesting that there's some sort of duplicate values. However, as you can see from the 'TotalSalesImpact' column there are no duplicate values.
I've been getting this error quite a lot in this dashboard and I'm really confused as to why I'm seeing this. Any help would be massively appreciated.
Hi @tomprice
This is because of the blank value.
