When getting data from the bank regarding outgoing payments, an end2end reference is included in the data
This reference is generated from the original payment journal, and the reference can be found on both journal lines, the payment journal line and the posting journal line
If for some reason the payment journal has been cancelled, reapproved , manipulated or etc. then it is possible that the reference numbers on the payment line has been changed, if this has occurred, the Reference match will no longer work
One solution is to manually match each line, by selecting payments in the lower part of the posting journal, and settle against the corresponding payment journal line
Another solution that can also be used, if the bank is not able to deliver the original reference, is to add the Automatch method AmcBankMatchRulePaymentAmountDate to the automatch setup used for this own bank account.
