Transactional RFC (tRFC): You can also submit Remote Function Calls when the target system is not
available. For example, the connection to a partner system may have been interrupted or the partner
system itself is not currently active.
The function module is flagged to be run asynchronously. It is not executed immediately, but the data
passed with EXPORTING or TABLES is stored in a database table.
Automatic job scheduling is performed. The job starts the relevant function module(s) in the partner
system.
You set parameters for the relevant connection via the table RFCDES:
--> suppress background job if communication error occurs
--> attempt to set up until system instructs otherwise
--> break between two attempts
