I have a Project with Billing Type = Fixed Bill, Milestone and a Billing Schedule attached to it. According to the Billing Schedule, the first bill should be 10% of the whole SO when Task 1 is complete, 50% when Task 2 is complete and 40% when Milestone 2 is complete. (Task 1 & Task 2 are under Milestone1). But, when I set Task 1 on the billing schedule to 'Complete', and click on Next Bill on the attached Sales order, the invoice is generated for the whole amount instead of 10% of the amount. Any idea why?
