The “ERP Integration Service” and “Financial Utilities Service” are utility web services that provide external web service operations for automatically performing different tasks. Such as:
a) Managing data files for import
b) Launching Enterprise Scheduling Service jobs
c) Downloading Enterprise Scheduling Service job details
From a functionality standpoint, the ERP Integration Service is much more flexible. Additional operations are included that support value-added features such as callback notification.
The ERP Integration Service supersedes the Financial Utilities Service. The Financial Utilities Service is deprecated.
New Oracle ERP Cloud customers should not use the Financial Utilities Service. To support backward compatibility, only customers who previously adopted the Financial Utilities Service in a production setting prior to the availability of the ERP Integration Service should use the Financial Utilities Service.
