Because transaction information sources of different channels and products are different and the message registration rules are not uniform, remittance messages of banks in different areas have poor adaptability to a universal remittance message standard (SWIFT standard) in content and format, and therefore, the remittance messages need to be checked through the SWIFT standard.
The method for checking the message in the related technology comprises the steps of firstly matching the message item with the SWIFT standard, determining the message item which fails to be matched, replacing all information contained in the message item which fails to be matched with null, and then sending the message to an opposite bank or a financial institution through the SWIFT network. However, emptying the content of the unverified and unverified message items can cause message information loss, and affect the accuracy of the remittance message received by the opposite bank or the financial institution. In addition, the existing method for checking the remittance message does not consider the influence of the splitting of the transaction information on the message format, so that the problem that the message is returned due to the abnormal message format easily occurs, and the timeliness of receiving the remittance message by an opposite bank or a financial institution is influenced.
