A known issue is a problem or concern with a CDISC standard that CDISC is aware of, and may be working actively to mitigate or resolve. Unlike errors or errors that affect conformance, known issues have no obvious solution when they are first identified; and some known issues may prove to be irresolvable.

Short Name	"COUNTRY" Terminology Change
Affected Standard	SDTMIG v3.1.2 SDTMIG v3.1.2, Amendment 1 SDTMIG v3.1.3 SDTMIG v3.2
Description of Codelist Change	The SDTMIG v3.2 and earlier versions list the CDISC SDTM codelist "COUNTRY" as the terminology codelist to use for the Demographics domain variable COUNTRY. This codelist was retired in 2016-09-30 (Package 27) because it duplicated the ISO 3166-1 alpha-3 codes for the representation of names of countries and their subdivisions. Maintaining the SDTM "COUNTRY" codelist was not reasonable, since it duplicated content maintained by ISO.
Standard with Codelist Change	SDTMIG v3.3 lists 3166-1 alpha-3 as the codelist for the COUNTRY variable

Affected Variable	Codelist in Published Standard	Replacement Codelist
DM.COUNTRY	CDISC codelist "COUNTRY"	ISO 3166-1 alpha-3

Impact of Issue	Coping Strategy
For submissions using CDISC CT package 27 or later, the CDISC SDTM "COUNTRY" codelist is not present.	Use ISO 3166-1 alpha-3. Click the online browser link from https://www.iso.org/iso-3166-country-codes.html
For submissions using CDISC CT package 27 or later, submission values that were prepared using the CDISC SDTM "COUNTRY" codelist for DM.COUNTRY may not be those in the current version of ISO 3166-1 alpha-3	Most values will be identical, but should be checked.
