Quotation Quantity Vs Sales Order (VA02) Quantity. (P2 Scenario)

Hi Team,

We have a P1 scenario where we maintained all the configurations to restrict the user from placing more quantity in sales order as compared to Quotation.

But now the user made the changes in Quantity (increased the quantity in VA02 which is more than Quotation) and saved it. I tried myself doing that and yes it happens that the system doesn't check the reference quantity in VA02.

I want to restrict users from adding more quantity in VA02 with reference to Quotation (They can make the changes in VA02 quantity but it should not be more than what is mentioned in Quotation).

The below Screen shot is for reference.
