Hi Ahmad,
I didn't remember the reason. but i faced the same issue in my previous project.
if you have screen shot please share the screen shot.
but you no need to worry about debugger. this kind of error comes rarely.
for 2 issue, by using RSPC_PROCESS_FINISH you can continue your process chain.
to run above program you need to required details from table RSPCPROCESSLOG.
Log id,process type, time and date.
From you process chain you need to get log id and instance name.pass these two values to table - RSPCPROCESSLOG. then you will get above 4 details.
Thanks
