Our customer required a solution in Oracle Payables for invoicing and paying a high volume of "one-time" payments via an interface. They didn't want the corresponding suppliers created as Suppliers in Payables. Oracle eBusiness Suite standard functionality did not meet requirements for the "One-Time" supplier. The solution was to create a single nominated One-Time supplier and provide actual supplier details (or employee details if paying employees) on the Invoice itself as Descriptive Flexfield data. 
One Time Supplier Process
Our customer required bank account numbers to be validated at data entry according to local bank account number algorithm.
I.e. In New Zealand bank account numbers are of the form AA-BBBB-CCCCCCC-SSS where:
AA = Bank Number
BBBB = Branch Number
CCCCCCC = Account Number
SSS = Account Suffix
A given bank account number needs to have a valid combination of Bank, Branch and Account number.
