Expressions that yield variant data-type error message in if statement
I'm tryingto create a custom column that checks some dates and returns "LATE" if it meets criteria or a date otherwise.
My formula goes as follows:
Actual Start =
IF(ISBLANK(RELATED('Sub Project w Activities'[Actual Start])) && 'Activity History'[Latest Customer Agreed Dispatch Date]<=TODAY(),"LATE",RELATED('Sub Project w Activities'[Actual Start]))
In simple terms, if actual start is blank and latest customer agreed dispatch date is before today then it's late (refers to activity), if however actual start is there I just want to show it. I've looked through form and previous issues indicate using FORMAT but I don't see where to use it, all my dates?
