With repeat purchases, you offer the facility to add %y and %m in the Description to dynamically add dates to the description each month. However, in the Supplier Reference field, the %y and %m does not do anything. With a repeat purchase, frequently there is no unique supplier reference and the best thing to enter there would be "Subs %m %y" or similar so there is a meaningful Supplier Reference automatically. This would be useful for anyone who finds %y %m useful in the Description field. As you already have this functionality working with the Description field, I would hope this is an easy additional feature to add into the Supplier Reference field also.
