> Unable to sign the invoice due to: unable to generate qr code for the provided invoice xml document

hello brother hopefully you would be doing well  
i have some queries about prepayment and its adjustment invoice

1:can we use single prepayment invoice in multiple adjustments if yes then how because in xml implementation documentation we can use multiple prepayments in single delivery invoice but not single prepayment in multiple adjustment  
2:secodly during providing the invoice data of prepayment we are providing the tax category and code of the prepayment invoice while there could be a case when we have one item of Z category and one item of S category  
then which tax category we should provide?
