1. Set OM Reservation Time Fence = Null

2. Available Quantity to Reserve : 18

3. Create an Order with schedule ship date as 01-Jan-2015 ( SYSDATE- 10 -Dec-2015)

4. Update the Reservation_Quantity with same as order quantity (1)

5. Available Quantity to Reserve is reduced : 17

Test Case 2

================

1. Set OM Reservation Time Fence = 5

2. Available Quantity to Reserve : 17

3. Create an Order with schedule ship date as 01-Jan-2015 ( SYSDATE- 10 -Dec-2015)

4. Update the Reservation_Quantity with same as order quantity (1)
