Customer VAT numer on invoice

Hello,

I’m testing some features, and I miss a few details. Can you clarify this?

When creating a company in the CRM module, I’m not able to add the VAT / TAX number in any field. This is mandatory on all the invoices in Belgium. Now, when I create an invoice on that specific company, I have the following errors.

-The company address is not shown or submitted from the database
-The VAT / TAX number cannot be added on the invoice (if applicable).

Can you check what can be changed?

Thanks in advanced!
