What is Transactional and Queued RFC (tRFC/qRFC)?
Asynchronous RFC variants that guarantee exactly-once execution (tRFC) and in-order processing (qRFC).
Outbound queues are monitored in SMQ1 and inbound in SMQ2, while tRFC calls appear in SM58. Stuck queues block downstream data such as CIF or IDocs. Queue monitoring is part of integration hypercare.
