RESCON ( <target_system> ).
RESCON resets the RFC context of the current RFC destination of the test script containing the command.
RESCON ( <target_system> ) resets the connection to the specified target system.
Depending on the release and patch level of the target system, this may be relevant in the context of function modules and inline ABAP. By forcing the connection to be reset, you can circumvent limitations caused by a restriction of the number of subroutine pools (36) that can be generated.
