Q&A with Will:
Q: I am looking for some help with the POS to Fin exchange. There is an error 3140 and the exchange log states status error with tax line, cannot be same as txn code? Where should I go to find fix?
A: Most likely the problem is how the accounts are mapped. Go into Company Preferences and under Financial Review the Account Mapping. Most likely you have listed an account in there that is creating the error. Examples are putting sales tax payable in the wrong box.
