Why address_style is null in ap_supplier_sites_all?

Hi Gurus,

We need to create a payment template which contains supplier data entered in ap_supplier_sites_all. Depending on suppliers, the template must be different.

So the idea was checking the address_style in ap_supplier_sites_all and depending on the value, the template would choose or not the other fields (addressline1...).

However, we see that most values of address_style in ap_supplier_sites_all are null. Can anyone explain why? In case it is useful, we don't user any custom style, just the address style by default (POSTAL_ADDR_DEF).

Thanks,
