I recently upgraded a customer from 4.50 to 2016 with JobOps. Today they tried to override the sales tax on a Sales Order (Sales Order, Totals, Tax Detail). They are able to override the tax amount and then save the order but when they reopen the order, the sales tax reverts back to the original amount. The change sticks on my system without JobOps, so I am not sure if I am missing an option somewhere or if it is a JobOps issue. I couldn't find anything on the knowledgebase. TIA
