Need a file based integration functionality (automation required)

Customer has set of data which needs to be uploaded in FCCS application (budget data) without any manual intervention. SmartView is not helpful here and we have has requested the customer to provide the data in prescribed format so that we can directly import the data into the application. Unfortunately due to huge volume of data, Client/Customer could not accommodate and they are requesting Oracle to provide an alternate solution to consume the data as it is without massaging it.
