Require to show the tax registration number in the Printed invoice

Content (please ensure you mask any confidential information):

Hi,

I had fill in the tax registration number in the Customer Profile -> Tax Profile -> Tax Registration -> Registration Number. However, the field is not in the existing code of the standard invoice.

I found that the value is stored in the table "zx_registrations" under the column "REGISTRATION_NUMBER".

Would like to seek assistance on how to combine the table with the existing code of the standard invoice.
