Payment Advice is not sent to few vendors in the payment run

Hi,

Payment advice note is not emailed to few vendors in the payment run. I have checked the program and variant in printout tab of F110, it has the print payment advice note box checked. I have checked the vendor master data of these vendors, I could see email configured in correspondence tab and communication tab. Could you please help me on to find out the reason for payment advice note being not sent to only few vendors in the payment run.

Thank You.
