If Destination Sales Tax applicable is unchecked in common parameters, then, how the tax code is defaulted on SO line apart from Item sales data? What are the tax code defaulting priorities in this case?

Thanks,

Even though the Destination Sales Tax applicable is unchecked in common parameters, you can still check the 'Tax parameter' and choose different 'search sequences' out of 6 available in LN. It works...
