SG has not been assigned to a country group for legal regulation KOR

Dear GTS Experts,

Sorry if this a very basic question but I searched allot can't find the solution.

I am receiving below error message under legal control country group/control group when looking at the log for blocked documents:-

SG has not been assigned to a country group for legal regulation KOR

Message no. /SAPSLL/CON_CORE139

I checked the configuration country SG assigned to country group B and country group B is assigned to legal regulation KOR. Also checked the determination strategy, everything is fine.

Can someone please suggest if I am missing anything or possible cause of this error.

Thanks In advance,

Davinder
