AR Business process is as follows: Invoices are issued. When payment is received, it is posted using F-26, with reference to customer but no specific invoice. F-32 is then used to match payments against invoices, and clear them. When trying to clear foreign currency customer items in local currency we receive error message F5263 "Difference is too large for clearing." We have set tolerance levels at the highest possible amount in OBA4. Please advise.
