Sending IDocs in Parallel

IDoc communication with transactional RFC (tRFC) uses all available dialog processes on the application server transferring the IDocs to the communication layer. tRFC parallel communication does not depend on whether IDocs are first collected or transferred immediately.

IDocs should be transferred to the communication layer on an application server with a sufficient number of dialog processes.

Make sure you specify a sufficient number of dialog processes on the receiving R/3 System. The number of dialog processes should not be less than the number of dialog processes on the sending application server.
