In this document I would like to collect a set of principles and how-to's when working with the complete delivery feature for sales orders in SAP Business ByDesign.
Background: For sales orders marked as 'Complete Delivery' on header level all sales order items with the same requested date and delivery rule 'Single delivery - full quantity' are assigned to the same delivery group. Automatically the delivery rule 'Single delivery - full quantity' is proposed for new items.
The complete delivery flag has impact on the following two process steps:
How does the availability check with complete delivery work?:
How does the release of sales orders to 'Outbound Logistics' work?:
The complete delivery indicator simply ensures, that all items of the same delivery group will be released at the same time. That means: if only one of the sales order items of a delivery group has a red ATP status, no item of that delivery group can be released.
What does this mean business wise? To simplify the discussion I will for now focus only on scope of check 'Stock'. The above described ATP behavior shall ensure, that those items, that are fully available, get a reservation for the requested quantity. This ensures that other order do not 'steal' those quantities.
Remark: In case only a partial quantity is available, no reservation is done for those items. This however then also means, that this quantity is still available for other sales orders and it will be more difficult to get a confirmation for the remaining parts.
Now the tricky thing is, how to ensure that complete delivery orders can be shipped at all, especially when there is a mix of complete delivery sales orders and other sales orders with multiple deliveries.
Let's assume that a customers is using the confirmation update run, sorted by requested date. Let's also assume for a moment that all items have a requested quantity of 1 ea.
The following table shows the ATP result after the confirmation update run:
Product | Inventory | SO1 + 5 days | SO2 + 10 days |
---|---|---|---|
A | 2 | Green | Green |
B | 1 | Green | Red |
C | 0 | Red | - |
We have two complete delivery sales orders, one requesting products A,B and C 5 days from now, and a second one requesting only products A and B 10 days from now.
Currently it is not possible to ship any of these orders, because no order has a confirmation for all items. Now there are multiple ways to react on such a situation (which in any case is a pure business decision that cannot be taken by the system):
Remark: It could always happen, that after inventory of C gets updated and before a new confirmation update run is triggered, a new sales order for C gets ATP confirmation.
Now coming to the more complex scenario, where item quantities are bigger than 1 ea. The major difference is that for complete delivery orders, partial reservations of quantities are not supported. As a result it is a little more difficult to get a confirmation for complete delivery orders. Again SO1 has an earlier requested date than SO2 and the table below shows the result after the confirmation update run sorted by requested date:
Product | Inventory | SO1 Req. Qty | SO1 ATP | SO2 Req. Qty | SO2 ATP |
---|---|---|---|---|---|
A | 3 | 2 | Green | 1 | Green |
B | 1 | 2 | Red | 1 | Green |
As said, SO1 gets a red ATP for B, because of the Single delivery - full quantity' delivery rule. Since no quantity is reserved for a red ATP the quantity of B is still available for SO2. In that case one could release SO2 to outbound delivery execution and now SO1 has to wait for 2 new parts.
Again it is a business decision if SO2 should be released or not. However there is not a perfect way to tell the system that the inventory of B should rather be reserved for SO1.
As a consequence one should be very careful using the complete delivery feature for those sales orders with a item quantity close to or higher than the average quantities, in which a product is supplied. It will be very hard to get confirmations for those items. This is of course also true for items using the delivery rule 'Single delivery - full quantity'. So the description also applies for non-complete delivery orders using this item delivery rule. However in combination with complete delivery orders it leads to a slightly more complex situation.
