Is the latest SDTM CT dated 2017-12-22 supported by Pinnacle21? I notice that it is not available at Pinnacle21 site (https://www.pinnacle21.com/downloads/cdisc-terminology), and when I try to feed the validator the file from the NCI site, the validator does not seem to use it. Any explanation?
The validator uses a modified form of the CDISC Controlled Terminology (i.e. things are changed by Pinnacle21). That is probably the reason why you can't use the feed from the NCI site. I am afraid you will need to wait until Pinncacle21 publishes its modified form from the download site.
