Ok, we've been importing EDI orders into DBA using the Sales order import add-on.  Many of these EDI orders come in with sales tax as part of the total order.
 
We've been converting the EDI orders to sales orders.  We go into SO and print the ack.  But although the customer AR record is set for Taxable=Y and a specific tax authority has been entered, the ACK is not showing the tax line (yes print freight and tax are =y).  The freight shows up but not the tax.  Tax was correctly imported via EDI, the EDI program shows the customer is set for taxable.
 
Why are we not seeing the tax get added to the SO for these orders?

HELP?
