While evaluating OpenERPv7 I was registering a customer payment and I noticed in the "Pay Invoice" screen, there is not an option for "Pay Difference".
The documentation online shows that there should be a drop down below the "Difference Amount" that asks how to handle the difference. However, I do not see this option anywhere, nor does the Difference Amount actually display anything except the number zero.
How do I enable this feature? Am I overlooking something?
