The RFC adapter maps the following RFC calls to XML messages and the other way around:
- Synchronous RFC calls (sRFCs) in messages with quality of service Best Effort (BE)
- Transactional RFC calls (tRFCs) in messages with quality of service Exactly Once (EO)
- The receiver RFC adapter can also process messages with quality of service Exactly Once In Order (EOIO). They are mapped to transactional RFC calls (tRFC).
