Hi Adhiyan,Thanks for your respond, I have resolve that issue by
selecting an action which I have forgotten to pick, I have selected
'normal execution' and the warning sign has now gone. But the main
problem remains the same that workflow would run upon restarting it but
after leaving it to run on schedule, it display the same error which is
the link leading from split to exclusion remain blinking. Does this
means the data that is flowing from the split does not exist so there is
no SMS or email...
