Dear Unilever,
Please find our response below:
SAP system will create the Invoice document, we wanted to know, SAP system will generate the IRN number and send it to FIRS for validation? or Once FIRS system receives invoice details and validate then FIRS system will generate the IRN number and will send back to SAP system? The IRN will be generated by the SAP System before sending it to the FIRS.
For QR code SAP system will generate the QR code and will send QR code link in JSON file to FIRS? or Once FIRS system receives invoice details and validate then FIRS system will generate the QR Code and will send back to SAP system? The QR Code is not part of the payload sent by the SAP system. Instead, it serves as an additional security feature on the printed or rendered version of an e-Invoice to prevent tampering and eliminate bad actors. The cryptographic key used in generating the QR Code originates from the FIRS root server, enabling FIRS to validate both the authenticity and specificity of each invoice.
