@CDAdeveloper
Did you try to validate it through sdk or from zatca sandbox?
I see all amounts are zeros???

@mohdzeeshan5c0 Thank you for your response, many of the invoices with zero amounts were accepted by Zatca, the zero amounts are irrelevant.
Some invoices came with this situation, and we do not know the reason!!
