I'm using SSRS 2008
and am trying to create an expression
where if date field A is greater than date field B or date field A is NULL then this filter will select this record. How do I do this?
I tried this expression to select NULL
date fields, but it is not working. I set the datatype to "Text" for now--should I set this to boolean instead? If so, then how can I modify this expression?
=iif(isnothing(Fields!A_date.Value),"yes","no")
