I do not understand the relation chip between Submitted vs Billable hours on the Project Approval entity.
Lets say the Resources have submitted 8 hours work for multiple days. When a Project Approver looks at the Time Entries for Approval view, they see Billing Type, Submitted (hrs) and Billable {hrs). The Billing Type is set to Not Available and the Billable (hrs) is set to 0 on all these records, with the Submitted {hrs) set to 8.
