We use Null values in some of our studies, but so far, when we import the xml-files into SAS, the fields containing Null values show up as missing an entry.
It would be great if we could differentiate in SAS between Null values and truly missing information.
Does anyone know what we need to do in order to make SAS recognise OC Null values?
Any help is much appreciated.
P.S. We use OC 188.8.131.52 and SAS 9.3
