3272875 - System is Returning Different Dates When You do Manual ATP Check and When You Execute The Confirmation Update Run

You have set up your system to use the Confirmation Update Run and created a RUN XYZ (XYZ represents the Run ID). When you execute the Run, it updates the Availability of your Demand (Sales Order) with the Date dd.mm.yyyy (dd.mm.yyyy represents a calendar date). However, when you same ATP check manually for the same Demand (Sales Order), the system returns a different date xx.mm.yyyy (xx.mm.yyyy represents a calendar date).

Hence, you would like to understand why the system is behaving this way.
