NTI reported the following issue -

1) Create a calendar with custom working hours - for example, 7.5 hours per day

2) Create a resource (optional to assign the resource calendar to this custom calendar)

3) Assign this resource to a task with duration of 1day, and edit Task calendar to the custom calendar

4) Planned Units for the resource assigned to the task is only 7h/d instead of 7.5h/d

Attached the test sp.
