Best approach to know how much in an order has been paid

[Alejandro Villamarin]

Hello everyone,

I'm wondering what is the best approach to determine the amount overdue for an order, that the total - paid

Looking at the model, it looks like I have to go through each line, then through each payment event and then determine the amount paid from there....isnt' there a simpler way to do this?

Thanks!
Alejandro
