Where is the column payment_method_lookup_code in R12 for the vendor sites

Hi,

Where is the column payment_method_lookup_code in R12 for the vendor sites ???

In 11i the PO_VENDOR_SITES.payment_method_lookup_code has check or wire ect.

but

in R12 this columns payment_method_lookup_code exist but is empty.

In R12, we flag in the screen  the "payment_method" column.

Can anybody say to me in what table is the column " Payment method " for the vendor sites in R12 ???

Thanks.
