Old AR Invoice address getting updated after customer address update

Hello all

We are performing address update on the customers using FDBI in Oracle. When the update of address is performed on the customer, existing invoices with old address are updated with the new address. Has anyone faced this issue and are there any solutions to avoid this issue ?

This is a major AUDIT issue as the invoice image shows the new address where as the actual invoice would have been sent to the old address.

Thanks
