Hello,

How can I add a no data field to an attribute table (no data and not a value of 0) ?

Either make a field Nullable in the field properties or you maybe mean how to turn zeros to Null?

I'd say field calculator with a python statement like 

if !Field1! == 0: 
    return None
else:
    return !Field1!
