R03 - Unable to Locate Account : Account number entered did not correspond to an actual bank account so the Forte was not able to pull funds. Most likely there was an error in either the bank account or routing no. Please contact the donor to confirm the bank info

If 'Parent Transaction not found or in Settling State' error appears, it means that the parent transaction, (which can be $1 the transaction processed for recurring setup) has been voided or still in settling state. Due to this the upcoming transaction is also rejected. We suggest to customers to cancel all the remaining transactions and set-up a new recurring transaction.
