This is basically standard SAP functionality under Multiple specifications functionality. With that process you can specify what country a material is Ok for or not ok for.
Multiple Specifications in Inspection Planning - Quality Management (QM) - SAP Library
Otherwise, without this, there is no standard way to implement what you want.
However, since you are using an interface between your LIMS and SAP, you can have your system, based on values in the file transfered, take certain values from the file and directly update the batch characteristic values, (MSC2n) and record the countries it's ok for. It would simply be a mult-value characteristic. But the data for it comes from the transfer file, not QM. There would basically be nothing visible about this in the inspection lot.
