I have 2 clients and the only thing in common is that this is happening since the Year-end IRD.
One is on Version 2013 and the other Version 2014.
If they change a line on a Sales Order the totals go to zero and print zero. I have verified that if we change the Sales Tax code for the order and change it back, this corrects the totals. I have run the Sales Tax Recalculation utility at both sites and they still encounter the problem.
Any ideas?
