License determination strategy based on a customer

Dear Forum members,

For one of our business processes, we would like to determine licenses based on the customer group or rather, block the SO's in GTS based on customer group. Any suggestions?

One idea I have is to create a license determination strategy based on country and customer, where we would be able to maintain determination strategy based on country and customers belonging to a a particular customer group. But the challenge here is that SAP GTS standard does not provide this access(Speaking about the CD01 to CD21 in determination strategy) and we need to insert this field in the access sequence and use it in the determination strategy, which may or may not be the right thing to do. This is just a thought.

Any ideas or suggestions from the experts...?

Thanks
