There appears to be a significant difference between how NAV handled deferrals and how BC does it. When you created a deferral template in NAV you could setup a default schedule with the percentages of what should be recognized in each period.

Business Central does not have this functionality and I think that this is incredibly valuable to have so that clients don't have to populate the values for each month manually when they are using User Defined. Some clients need to be able to control how much revenue is being recognized in each month but not by necessarily days in the period.

Would love to see this functionality added to BC.
