R12.1.3: Payables Open Interface Import performance issues

With all of the issues that have been rattling out of our R12.1.3 instance, it is good to learn about one in advance of having it happen to us when we can least afford it.  In that light, today's post is about the patches located within the My Oracle Support page "Performance Issue In Payables Open Interface Import" in note ID 1900462.1 where an import of several million lines did not complete in a timely fashion.  Do you want to wait until your Import had this many lines, or do you want to prevent disaster and plan for these patches?
