How to blank out a field using OAF personalisation in iProcurement ?

Hello,

We disabled Express receipting as many of our requestors are receiving full quantity by mistake.

Now we are facing the same problem with normal receiving as well.

When the requestor clicks on 'Receive items' menu in iProcurement, the 'Receipt Quantity' is already populated with 'Available Quantity'

We wish to blank this out, so that the requestor keys in the quantity himself rather than a default.

By defaulting a field, the requestor is overlooking the quantity and receiving all the available quantity.
