LBORRESU value not found in 'Unit' extensible codelist

Did you add it to the corresponding codelist in the define.xml with def:ExtendedValue=“Yes”?
The software should look it up there.

We are getting the CT2002 issue reported on LB records with an original unit of x10^3/ul which is not in the code list, nor is there an obvious duplicate. There is the synonym of 10^9/L but this is not the reported unit and converting seems less “appealing” than explaining.

What would you suggest the cDRG explanation be for this scenario?
