Can we set Receipt Quantity to Default blank or Be Editable via VBS in Orders to Receive

Summary:
In the RUI "My Receipt (New)" → "Orders to Receive" screen, the Receipt Quantity field is automatically populated with the ordered quantity by default.

There is a requirement to have this field default to blank so that users can manually enter the quantity or display it using "Show Receipt Quantity." However, when attempting to modify this behavior using VBS, the field is locked (indicated by a lock icon) and cannot be changed.

Guidance is appreciated on whether it is possible to remove this restriction or configure the field behavior.

Thank you,

When partial receipts are required, the defaulted full ordered quantity increases the risk of processing an unintended full receipt.
