Supplier Business Identifier plus inclusion on Tax Reports - #7 by lubos)
In the latest version (21.11.66), I’ve removed generic
Business Identifierfield from customer form. Generic business identifier field is not the direction I want to take.Instead, country-specific custom fields should be created (ideally on localization server so it will be automatically available to all users).
Then this custom field should be leveraged in country-specific reports.
Any existing Business Identifiers have been addded to the Billing Address.
