1. How are the start and end dates determined?
When Task A is cloned to the project 'Development' the start date of the task will be 24th Oct, 2018 and end date will be 26th Oct, 2018.
2. How are the start and end dates defined for the task in the project after cloning?
When a template is cloned to a project all the work items will determine its start and end dates based on the project's start date, counting the Start After days and Duration defined in the template.
3. What if I don't mention the 'Start After' field for a work item in my template?
If the work item doesn't have Start After days and only the duration, then the work item will not hold any start or end dates. Instead, it will just have the duration.
4. What if I mention only the Start After days without the Duration for a work item in my template?
If the work item doesn't have Duration then by default we will assign the duration as one day to the work item right when it is created or updated.
