How to restrict duplication of BOL number for ASN of same Supplier

Question

Hi All,
Is there any way to restrict using same BOL(Bill of Ladding) number in for the 2nd ASN of same supplier.
BAdi for validation framework will only make it Mandatory and does not restrict using same BOL number 2nd time.
Regards,
CK
