The number of different function modules and inline ABAP blocks that can be called through an RFC connection is limited to 36 (this is a limitation of subroutine pools). The RESCON command allows you to circumvent this restriction by forcing the connection to be reset.

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.
