Hi Alex_Int
I suspect you may have to re-create the recurring transaction.
My guess is this error was caused by MYOB making a change that regards every invoice as has having Freight (whether it does or not). So the absence of a Freight linked account causes the error.
However as your recurring transaction was built before this change, the freight field might be missing entirely. Create a new purchase recurring transaction and test to see if it works, if not delete it, if it works, delete the original recurring transaction template.
