Understanding OSA Interfaces
Before reports can be output using OSA, you must define the interface. Typically, once defined, OSA interfaces are associated with specific reports or batch versions; however, you can override the default OSA at runtime. You can select from any valid OSA at runtime, although the results might vary depending on how robust the OSA. OSA interfaces can be associated in the same way as default printers with:
Environments
Hosts
Users or roles
Depending on the report output requirements, you might need to define multiple interfaces.
