Dear Minu,
As it is shown, the FM "RFC_START_PROGRAM" is not exist in the system. Normally, the function "RFC_START_PROGRAM" is exist in an external system(RFC Server program) i.e. rfcexec in RFCSDK, and this function is called from the client (R/3) system.
That means an R/3 system has no FM (function) "RFC_START_PROGRAM", hence the dump was raised by calling the FM "RFC_START_PROGRAM" inside of R/3 system i.e. CALL FUNCTION f1 DESTINATION "NONE".
So please check this once in the Z FM.
Thanks & Regards,
Manu.
