A customer has one unit in SEZ and another is a registered unit under India GST. Sales to SEZ unit is expected to be without payment of duty whereas Sales to Registered unit is taxable based on state codes.

The registered address of the Company is a taxable GST location with type = Registered.

While setting up system, if customer card is set with GST Customer type = Registered and a Ship-To address with GST Customer Type = SEZ, system does not permit marking 'Sales Order' to "Without Payment of Duty" even if the SEZ is selected in Ship-To and GST dependency is set to Ship-To.
