Bill Date

The date provided as the Bill Date for a Pre-Billed Labor entry will determine when that entry will be included in a post process.  If your intention is to setup a Pre-Billed Labor entry and have subsequent labor actuals applied towards retiring that amount, then you should be sure that the date provided pre-dates the labor actuals work date.   Further, the posting of the Pre-Billed Labor entry would ideally occur prior to the posting of the labor actuals.
