Stupid question about dates filtering using OR

[alecsonline]

Hi all, I already know it is a stupid question for you.... but not for me!
As per image below I have a column were a Cancellation is shown, if the item has been cancelled, or it is empty if the item is active.
 
I need to show the situation of the items that were still "active" on a certain date, for example reading the situation on 19/08/2018 I have to tell to PowerBI:
 
count the lines that have "DATACXLREALE" >19/08/2018 OR that have that field empty.
 
So the question is: how should I write the FILTER formula in order to translate the "OR" in DAX formulas?
 
In excel it would be OR(DATACXLREALE>19/08/2018; DATACXLREALE="")
 
Thank you very much in advance, Alessandro

@alecsonline its the same way 

Result = IF(OR(DATACXLREALE>19/08/2018; DATACXLREALE=""),STATOREALE1)

and then you can distinctcount the result column

Here is the DAX UG for that.
