Root Cause

• Mandatory fields missing in submission: The transaction file lacks one or more required fields needed for successful processing.

• Incorrect field values: Certain fields contain invalid or improperly formatted data that do not comply with interbank or payment gateway specifications.

• Invalid transaction codes provided: The transaction code used is incorrect or not supported by the payment network.

• Schema or specification mismatch: The file format or field values do not align with the latest submission requirements of the payment processor.

Troubleshooting and Solutions

• Review the submission file to ensure all mandatory fields are present and correctly populated.

• Verify that the transaction codes used are valid and supported by the payment network and gateway.

• Update the file structure to match the latest interbank or payment gateway specifications.

• Implement automated validation tools to check the correctness of data before submission.

• Retry the transaction only after correcting all validation errors in the submission file.

• Contact the payment gateway support team for clarification on accepted transaction codes and file formats if needed.
