Summary :
The SAP Note elucidates the function and management of the rdisp/max_wprun_time parameter, which curtails endless loops and unintended lengthy transactions by setting a runtime limit in dialog transactions. If a dialog transaction surpasses the designated time, signaled by rdisp/max_wprun_time, it is halted upon the subsequent ABAP/4 command. Programs that invoke "COMMIT WORK." regularly can extend beyond the prescribed time. Parameter adjustments should not be needed from its standard setting (600 seconds), and setting it to zero could precipitate system crashes by allowing perpetual loops. Users should also reference RZ11 for detailed parameter documentation.
Key words :
unintended long-running transactions, parameter rdisp/max_wprun_time sets, regular intervals resets, longer run times, parameter rdisp/max_wprun_time, rdisp/max_wprun_time parameter, running database queries, database query fails, rdisp/max_wprun_time seconds, work processes forever
