I am unclear what you are trying to do. Are you trying to run Prebills? Why are you deselecting all? Why are you using Billing Assistant?

1) I have used TS since about version 4. I was on version 2010 until 12/16. I have used primarily Billing Assistant for at least the last decade and the place to start when I want to run bills particularly if I am running more than one bill.

2) I was using it this morning to generate about 4 bills, one of which was going to be a bill to client in which I wanted to hold all time charges just this month and send an expense only bill (that is the subject of a separate post on the forum). In trying to debug the unexpected results from holding time charges on a bill run involving 4 clients, I noticed that I could clear all selections and I was hoping that would "reset" the selection process - it did not. It did show zero estimates charges but when I hit either generate bill or generate prebill (again testing) it ran all bills even though none are selected.

But ultimately, what had me using it this morning and testing different routes to the goal of running 4 bills was trying to figure out the unexpected result on deselecting all time charges on one client that was part of a batch of 4 bills to be run through Billing Assistant.
