We would like to import and validate our B2B xml invoices from OSuN/CMK on a regular schedule.  The only parameters available for the Validate Payables Invoices job request are Invoice Group and Pay Group.  Neither of these fields have unique values imported on these invoices. The other parameter options are From Invoice Date, To Invoice Date, Supplier or Party, invoice Number, Entered By.  None of these fields is unique to xml invoices either.
