As of now, when we click on submit button in ess.do the ticket gets escalated as an incident, now i would need to implement approval flow, for which i thought of creating a new submit button and when clicked the submit button it should go for its manager approval. How could i do it? Please assist as this little urgent. Regards, Madhu "Any help kudos are given"
