Backward Scheduling is not working during ATP

Hello

During ATP check the backward scheduling is not confirming the sales order on requested delivery date.

Ex:

There is enough inventory at location to cover the requirement.

Lets assume current date when order is being created as 9/11

If order is created with requested delivery date as 9/11 i.e. current date, system proposes confirmed delivery date 9/15 as below.

MAD = 9/11

PICK/PACK = 1 day = 9/12

LOAD = 1 day = 9/13

TRAN = 2 day = 9/15

So, the latest the order can be confirmed is by 9/15, So if I ask requested delivery date as 9/15 then it should be confirmed on that date. But the system is considering the MAD as 9/15 during backward scheduling and then adding lead time of 4 days in forward scheduling to confirm the order for 9/19.

If requested delivery date is changed to 9/14, then MAD is considered as 9/14 during backward scheduling and then add 4 days lead time in forward scheduling to proposed 9/18 as confirmed delivery date.

goods receiving hours at ship to location are 24/7 so no impact due to it.

We using GATP for transportation and shipment scheduling for sales order.

Regards

Kumar
