Alternate payee in document

Hi All

I have an issue that, Individual sepc indicator has been selected and account holder name aslo maintained in the vendor master data.

While running F110 - automatic payment program for the vendor, it is not conidering the account holder name which is maintained in the vendor master, it it generating with vendor name only.

Could you please let me know why the account holder name is not considered in the payment.

Thanks

Attipat
