I want to create approval workflow same as SharePoint out of the box approval workflow. I have created a flexi task assigned task to multiple users (we are getting these users from code). Now the tasks are getting assigned to each user simultaneously. But I want to assign task serially that is a task is assigned to first user and once it is approved then task will be assigned to next user and so on and if it is rejected at any level then workflow will be terminated. As of now I am not getting any such option. Please help.
