We often have an employee (well, multiple ones, but the principle is the same for one, I think, and it's easier to follow) working on several WOs at once for different quantities of different products. For instance we make part 132 in six different woods. The process is all the same - the machines don't know any different from one to the next (except in rare circumstances).  
 
For example, we may run the following:
200' 132Ash
200' 132Cherry
50' 132Mahogany
1500' 132Maple
100' 132Oak
300' 132Walnut
 
Someone told me in Nashua that DC-A/DC-C would split up the time based on how many WOs you were working on and how much product you made. Maybe it works in DC-A where you are entering completed parts at the same time, but we may have 10 sessions of logging in and out before ANY parts are completed, so we would need to use DC-C.
 
Is there any way built in to DBA to do what I need to do?
 
What we're doing right now is using a time sheet, manually adding up all the times and then manually splitting up the labor based on how much was made of each one and entering the labor as a BOM material in WO-G.

I have no problem with the labor being divided by the number of jobs. The problem is that the labor is divided evenly among the jobs rather than proportionally based on the number of completed parts.
 
Say I need 1 brass washer and 99 steel ones. I clock into both WOs, make them and clock out. 50% goes to making 1 brass one and 50% to the 99 steel ones, instead of 1% and 99%.
