Your own company BRN was not provided correctly.
Solution:
Go to Tax > Tax Entity Maintenance, please make sure you input only the New BRN number, do not include Old BRN into the Business Registration Number field.
Example of New BRN : 20060103XXXX
Do not key in as : 20060103XXXX (751600-A)

If the error shows BRN – BUYER, mean the customer BRN number incorrect.
