Summary :
The SAP Note details improvements and prerequisites for the parallel import capability of transport requests via the transport program (tp) and R3trans. It outlines that SAP_BASIS Release 700 or higher is required, with specific versions of R3trans and tp depending on the kernel version and operating system. For instance, R3trans version needs vary from 14.02.08 to 30.06.10 based on deadlock handling, database type, and operating system with corresponding kernel patches. Additionally, tp versions 372.04.10 or 375.30.10 are needed for kernel releases 700 and 710 respectively. A new configuration parameter "parallel = n" enables setting the maximum number of parallel processes, beneficial for ensuring performance gains during import, though SAP advises starting with "parallel = 2" and adjusting as necessary based on server and database capabilities.
