If won, then calculate difference between two dates
I'm trying to add a calculated column to calculate the number of days between two dates. However, I need to only calculate for those that meet a certain criteria.
The formula I tried is:
DiffCloseDate = if(Opportunities[Status]="won",(Opportunities[Actual Close Date]-Opportunities[Est Close Date]),"")
For the 'then' clause, I also tried
Datediff(Opportunities[Est Clsoe Date],Opportunities[Actual Close Date],Days)
The error I'm receiving is:
A single value for column 'Actual Close Date' in table Opportunities 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.
But, I don't want to aggregate the dates. I just want each row to perform the calculation.
Thanks for any help.
Are you sure that you are using a calculated column because the error you are getting is for a measure. If you use a calculated column, your formula would generate an error regarding "variant" data because you are trying to return a number and a string at the same time. Both have to agree in terms of the data type returned. So, you could do something like this as a calculated column (not a measure)
DiffCloseDate = IF(Opportunities[Status]="won",Opportunities[Actual Close Date]-Opportunities[Est Close Date],-999)
