Help for Aimeos

Hi, I am trying to add new field to customer (users - I am using laravel) table - Chamber of Commerce number (COC) alongside with existing VAT ID.

I read this forum and there are several topics regarding this, most of them are suggesting extending managers and items, which I find as an overkill for such a common thing (and I am also getting "AccessDeniedHttpException").

You also mentioned this can be done by "reference attribute items via the list table".
Can you please give me more information what does it mean exactly?

The easiest way is to store that information as customer property in the users_property table. You can manage that information in the customer panel of the admin interface.

If customers should enter this value in the checkout process, the easiest way is to extend the customer item/manager and the order address item/manager.

We will see how we can store arbitrary customer properties easier in the future during the checkout process.
