Invalid Simplified Invoice

Signing process
1

Dears All,
I’ve tried entering the serial number in the format “1-manufacturer|2-model|3-serialNumber,” but it didn’t work. I also attempted to decode the X.509 certificate, but I couldn’t retrieve the IssuerName or SerialNumber. What is the correct method to achieve this?

xades:IssuerSerial
ds:X509IssuerNameCN=PRZEINVOICESCA4-CA, DC=extgazt, DC=gov, DC=local</ds:X509IssuerName>
ds:X509SerialNumber1234567890123456789</ds:X509SerialNumber>
</xades:IssuerSerial>

Thanks for reaching out,

Can I kindly ask you to elaborate more about your concerns, and answer the below questions? to ensure comprehensive support as usual:

1-Are you using our SDK tool? If yes, JAVA, or .NET
2-Are you in Simulation env or Prod?
3-Did you review the Educational Library shared on ZATCA site?
4-What are the steps you are doing to sign the invoices?

Thanks,

Morning @Madleen

I hope you are doing well,

Please note that the developer portal is containing a static data, it’s only to make the understanding easily.

Can I kindly ask you try on simulation ENV?

Additionally, please note that a new release of the SDK published it’s 3.3.5, ensure to download it.

Let me know if you need any further assistance.

Thanks,
Ibrahem Daoud.
