R12 : Supplier scheduled payment date incorrect in AP invoice workbench

Hi Friends,

 

I have just come across 2 invoices where the scheduled payment date is wrong – both for Vendor# 4497 Ramset Australia.

 

Invoice 8284267 – invoice date is 02-04-2013 with payment terms of EOM + 1M + 15 days.  Scheduled payment date should be 15-06-13 but shows as 15-08-13

Invoice 8254811 – invoice date is 30-11-2012 with payment terms of EOM + 1M + 15 days.  Scheduled payment date should be 15-01-13 but shows as 15-08-13

 

I have processed a number of other invoices for this supplier today where the scheduled date is correct, including invoice 8278062 dated 07-03-2013.  This correctly shows a scheduled date of 15-05-13.
