I have a query where I Group By an Equipment Number field and then, for each equipment Number, return the Max (latest) Forecast Delivery date.
The problem is where one or more entries for a given Equipment Number has a Null in the Forecast Delivery date field. In these cases I need to return Null.
So, I need something like: "Return Max if there is no Null, otherwise return Null" for my Forecast Delivery field.
I have no idea how to do this Access so any help would be greatly appreciated.
Thanks very much.
