- Setup Interface Parameters
- Setup Profile Matching
- Setup Communication Methods
- Setup License Codes (for OXI interfaces)
- Setup Automatic Transmission Schedule
- Setup UDF Configuration

OXI Components for Dataflow External System to OPERA
The OXI Download Processor
Reads the external system download queue and creates an entry in the temporary XML table
- Performs data validation
- Performs conversion for all activated conversion tables
- Applies download defaults for unsuccessful conversion
- Writes a record into the OPERA API structure and from there the API populates the OPERA tables with the record

Business Event Configuration
- All OXI 2-way licenses automatically activate the external system and its business events. It is not necessary to have a separate business events license code.
- To run the 2-way interface, the external system has to be activated and configured
- The business events needed for upload have to be configured for the specific external system to create messages
Business Event Processor
- Every time a transaction happens through user input or automatically, a business event is created in OPERA.
- The business event processor transports the data from the business event Enqueue into the Outqueue.
