Banking Hours Work Around

"I am having issues with how the program is handlling the work around" for banked hours.  We started a job called banked hours.  The hours go in and come out of this "pretend", however when hours are paid out at overtime, the dollar amount that is left in the banked hours needs to be job costed to a current "real" job.

I was instructed to Debit the amount of overtime to Direct Wages and Credit Direct Wages for the same amount and adjust the Job Cost to the correct job.

E.g.

Direct Wages   Debit $600.00

Direct Wages                            Credit $600.00

Job Cost "Banked Hours Job"                    Credit $600.00

Job Cost "Murray Job"           Debit $600.00

The problem is that because the Direct Wages Debits and Credits = Zero.  Sage treats this as if the entry does not exist and nothing happens with the job costs.

The above is how I believe I was instructed to work around wages difference in Banked Hours however it does not appear to be working.

Do you have any suggestions or alternative methods?
