Determination of Tax Jurisdiction Code

Hi,

Even if I am not maintaining any Tax jurisdiction code for the ship-to-party system is able to determine the Jurisdiction code while creating Billing.

Please advice how this determination happens.I had an interpretation that only if we maintain Tax Jur for a customer it can be determined at the billing but in this scenario the determination is not happening based on the customer record.

Share your thoughts... Thanks in advance.
