Hi All,
I am creating a column with if condition to check if a column is "Yes", then calculate the date difference ,else show as N/A.
I get an issue with datatype here saying "Expression with variant data-type cannot be used to define calculated columns."
newcol=
IF('C'[PRequired]="Yes",
(DATEDIFF(LOOKUPVALUE( 'H'[IntakeDate], 'H'[Protocol Number],'C'[Protocol Number] ),'C'[SubmissionDate],DAY)),"N/A")
Can somone pls suggest on how to fix this?
Thank you
yes, then you maybe should not set it to N/A but to BLANK() and remove the ""& part again.
You have to convert the DATEDIFF result to a string, because N/A would be a string too.
Just put this in front of DATEDIFF: ""& so that it looks like this:
newcol=
IF('C'[PRequired]="Yes",
(""&DATEDIFF(LOOKUPVALUE( 'H'[IntakeDate], 'H'[Protocol Number],'C'[Protocol Number] ),'C'[SubmissionDate],DAY)),"N/A")
@lukiz84 : Using ""& in front works, but I am inturn using this column to calculate the average and median.
I am getting an issue with this column when calculating average.
