Hi Satish,
As far as I remember standard determination procedure LELOC is activated at Country/ Country Level and Country/Country Group Level. Can you please grab a screenshot of determination strategy for determination procedure LELOC.
Navigation Path:
SAP Global Trade Services >> General Settings >> Legal Regulation >> Define Determination Procedure for Active Legal Regulations >> LELOC >> Assignment of Determination Strategy.
If all the settings are in place as per your confirmation, I don't see any other reason for system to unable to determine active legal regulation.
regards,
