Changing Invoice Pay Site
We are completing our third Payables close after upgrading to R12.1.2, and we're having the same problems closing as we did at the end of the second month.
The system does not let us close Payables, but when we run the exception report it shows no exceptions. Digging further (and with Oracle's help last month), we found events in the SLA tables that Oracle said were a result of a Supplier Merge, and the way to address the issue was to run the Create Accounting for Third Party Merge. We had never run a Supplier Merge, so Oracle's cause was erroneous, but their solution did work.
