VK11 Pricing condition record creation (check sales area of customer)

How to implement a check for pricing condition record creation (VK11), that customer is extended to relevant sales area?

Currently when user creates condition record in VK11, giving his sales area, he is able to choose customer from different sales area and then save the condition record.

Is there any SAP note for it?
