Purchase to Order Scenario - Partial Confirmation Issue

Question

Hello Team,
We are using Item Category with Purchase to Order Scenario. When the Sales Order is booked, Purchase Requisition is Created. Sales Order Line is linked to the Purchase Requision/Purchase Order.
In this scenario, we are getting confirmation on Sales Order through PR/PO Initially.
Order Quantity     Confirmed Quantity
10                         10
Once we receive partial confirmation on PO let us say 7 system only confirms partially Sales Order.
Order Quantity     Confirmed Quantity
10                         7
Issue happens when our team does partial delivery to customer before receiving full confirmation from the Supplier. System blocks further update of confirmation on the line and it becomes impossible to make delivery to Customer for Partial Quantity.
I can think of two options...
1. Somehow when we receive Partial Cofnirmation, our Availibility Check should confirm 7 on Confirmation recieved from the Supplier and 3 from Delivery Date of Purchase Order. So this issue won't happen.
2. System should somehow allow Partial Confirmation even after Partial Delivery is done to the Customer.
Do let me know if you need any more details from my side.

Hi Kaushal,
i assume that you have special stock indicator in your sales order.
if you do not use confiramtion then all quantities are confirmed at schedule line level.
if you use confirmation e.x. 7 of 10 pieces then you will have confirmer 7 quantities in your schedule line.
if you create another confirmation in PO of 2 pieces and lets say different date you will see another schedule line in your sales order.
do your system works like this?
Is your third party scenario require a googds receipt for PO to move on to delivery?
Regards.
