As Provider I want to configure the PBA Online Store to ask tax registration number on the customer registration form.
However, the USE_TAX_REG parameter does not appear in the PBA Provider Control Panel at Product Director > Online Store Manager > General Parameters.
The USE_TAX_REG parameter is obsolete and is not used in the modern PBA versions. The documentation will be corrected in the future PBA updates.
Follow the steps below to force customers to specify Tax Registration Number/ID in the Online Store:
Log into the PBA Provider Control Panel
Go to Configuration Director > Sales & Financial Settings > Country Specific Settings
Click on the country for which Tax Registration Number should be required
Click Edit and set the 'If Tax Registration required for persons' and 'If Tax Registration required for companies' parameters to 'Required' if necessary.
Synchronize the Online Store at Product Director > Online Store Manager > Synchronization Settings.
