Use codesets to normalize display

Hello,

We currently use codesets to normalize NDC code descriptions in our clinical viewer. Lately, we have started receiving RXNORM codes and they were only displaying the codes in the viewer and not the descriptions. After a short investigation, I found that the RXNORM codeset in the registry was empty. After filling this up, it still didn't resolve the description of the drug.

The SDACodingStandard in the SDA is an OID and I see it in the OID registry and does point to RXNORM. 

Does anyone know where I can configure the clinical viewer to look at the codeset based on the SDACodingstandard?

Thanks!
