ATP check partial Quantity allocation to Sales Orders


Our client has three different sales order types for processing sales differently for the same materials.

While doing ATP check they have a order of priority i.e ZOR1 -> ZOR2 -> ZOR3 with ZOR1 highest priority.

For sales order type ZOR2 currently they donot have partial quantity allocation to sales orders.i.e if two orders, Order 1 created with 100 Qty and other Order 2 with 50 Qty and if ATP is 50 Qty.

System is allocating material to Order 2 which has order quantity 50 ( Which equals ATP Qty )

Now the client requirement is to configure system such that it does partial allocation to Order 1 ( order qty 100, where as ATP Qty is 50 ) i.e system should allocate even partial quantity to sales orders, that too in FIFO ( system should allocate ATP qty to order created first then next and so on )

Please let me know what changes i need to do to achieve the above functionality in SAP system.

    Hi Venkat,

    I think you require to do a setting in the SPRO for the same.

    SPRO -> sales and distribution->basic functions - Availability check ->Availability check with ATP logic -> Default rule for availability check , and change the checking rule as per your requirement.

    Dear Venkat,

    Please check the customer master for the customer which you have maintained in the 1st order. If the customer allows partial delivery, them the system will allocate the stock to the order which is created at first.

    At the time of ATP check(In Availability Screen), you do need to choose, One-time or System proposal, which will allocate the stocks partially to the 1st order as you don't have enough stock.

    Check out the settings in the customer master (for the customer in the 1st sale order) under Shipping Tab.

    Partial delivery per item D/A/B

    Max. partial deliveries >0

    (And more thing, you mentioned that sales document type is having priority. As of I know - there won't be any setting which will set particular sales document type with high priority. If you are really doing that kind of setting - update the same in this forum - it may help others..)

    Hope it may help you.

    (Venkat: Has your issue solved? Kindly update in the forum - if your question is answered)
