3rd party process PO/SO user exit

Hi Experts,

I would like to request your help on below scenario. I'm configuring a 3rd party process where vendor sends an Order Acknowledgement (EDI-855) which updates purchase order with AB (order confirmation). Basically tentative delivery date and quantity. This change reflects in sales order schedule lines automatically. I want to prevent the change of sales order update for a business reason. Could you please provide which user exit exactly carry this functionality. Can I restrict this by configuration (Standard)?

Please let me know if need any further clarification on my question! I want to restrict only AB (Order Acknowledgement/confirmation) update on sales order.
