In Build 71 an issue was identified when using the Tax by Item Category feature set to Taxable and a blank Tax Schedule ID. If a transaction is entered for a tax exempt customer, then a non-existent exempt tax schedule ID of all blank spaces followed by an “X” (for exempt) in position 15 is used for line items belonging to that Item Class. This tax schedule is the result of DynamicZip trying to make an empty Tax Schedule ID field exempt.
To avoid this issue, either enter a Tax Schedule ID into the DZ Tax by Item Category Setup window, change the Tax Option to Base on Customers or delete the Tax by Item Class setting.
This issue does not occur in Build 72 or subsequent versions.
