ATP check with including puchase order

[former_member667290]

when we create SO with ATP check to reserve the qty of the currenct stock, we also want to know the future qty of purchase orders so that we can clearly know the supply and demand of these materials.

so we use ATP check with including purchase order, that users can reserve the qty of open GR purchase orders.

but when the status of that PO changed, the reserved qty before won't have effect, and can't create outbound delivery either.

there are two examples below:

1. there is one SO reserved 10 material qty of the open GR PO, which it's scheduled delivery date is 5/15. but this PO still hasn't goods receipt until 5/17, cause ATP check rule is "Include future receipts only" ( if "Receipts in the past as well as in the future" is set, it will be confused with current stock qty), so these 10 qty won't have effect and the ATP qty is now a negative. we should only reserve again by t-code V_V2, otherwise all the reserved qty can't be deliveried.

2.there is one SO reserved 10 material qty of the open GR PO, which it's scheduled delivery date is 5/15, but when the delivery date of confirms tab is updated by vendor, these reserved qty before will also be invalid.

please tell me how to resolve these problems?

Hi,

If the business wants to confirm the sales order quantity against the incoming purchase orders, then this always happen. The issue can be resolved only by rescheduling the sales order by running V_V2 everyday.

Alternatively you can suggest the business to exclude the purchase order from availabilty check(AC) in t.code OVZ9 and include shipping notification in it. When the vendor sends some materials confirmation, the purchasing can add the shipping notificatoin details in the purchase order and can create Inbound deliveries for goods receipt. By this way, only when the vendor ships the goods, the quantity will be taken into AC.

Thanks for your feedback, which is very helpful.

But now our system is only use GR after PO created, we didn't use inbound delivery flow. So could you tell me other solution without inbound delivery?

And is "Shipping notification" only refered to inbound delivery flow?
