Now do NAV show and handle capacity overload case

kiyac

I am testing how NAV handle capacity overload.

SO # Item due date Routing Capacity need
SO1 C 14/12/12 PACK 1000 hrs
SO2 F 14/12/12 PACK 1000 hrs

Routing: Pack
8 hours per day (Mon-Fri)
capacity =1
effecticient = 100

Here is my finding:

Version : R2 W1

1. If Capacity Constrained Resources is set
(MFG > Capacity > Setup > Capacity Constrained Resources )
e.g 100%
No. Due Date Starting Date-Time Ending Date-Time
C 14/12/12 22/06/12 08:00 13/12/12 16:00
F 14/12/12 30/12/11 08:00 21/06/12 16:00

2. If Capacity Constrained Resources is set
(MFG > Capacity > Setup > Capacity Constrained Resources )
e.g 80%
No. Due Date Starting Date-Time Ending Date-Time
C 14/12/12 25/04/12 12:00 13/12/12 16:00
F 14/12/12 05/09/11 14:00 25/04/12 12:00

Question : What is the logic for calculation of start date?

3.Without capacity constraint resource set
No. Due Date Starting Date-Time Ending Date-Time
C 14/12/12 22/06/12 08:00 13/12/12 16:00
F 14/12/12 22/06/12 08:00 13/12/12 16:00

Question : This case will be overload, there is no warning, so how do user know there is overload for work check in planning worksheet?
