PPR Rejected with error "Document Payee IBAN is required"

Hi Professional,

Need your urgent help , We are trying to create a PPR to pay our suppliers but payment gets rejected "Document Failed Validation"  with error as "Document Payee Bank Account IBAN is required".

I have checked all supplier bank accounts , IBAN is already present in all suppliers and account is also active.

Could you please advise what things should I check ?

Quick reply would be highly appreciated

Thanks a lot ....
