I am trying to build a workflow that has a task for a developer to build a file. After the file is complete, control will be passed to an Analyst to validate the file. I am using a flexi task for the Analyst to approve or reject the validation. But, what type of task would I use for the initial task where the Developer builds a file? I was trying to use the Assign to-do task, but I am not sure how the task is flagged as complete and move to the flexi task. Does this make sense?
