Calculating end-date base on start-date and display the reminder
Hello, I have searching this problem in the knowledge-base but didn't.
My problem is how I want to set the end-date is 7 days after start-date. Means that they have 1 week (7 days) to finish the task, and after that the reminder will be displayed if the task didn't complete during time given.
Can I use end-date & start-date fields as date, summary, calculation or what.
Please advice me.
