I usually make adjusments like this through enter direct cost in job cost.  You can enter the adjustment as a negative against your job using Job Cost Only.  Then using GL only, you can enter the adjustment as a positive agiainst your GL account.

Generally, the rule to follow is to correct the coding or allocation of costs in the source where the costs originated.

If the costs you refer to originated in Accounts Payable, use AP > Tasks > Change Invoices to edit the distribution lines to delete the coding to the job and/or any commitment and select the appropriate overhead GL account you wish to use. Invoices that have been paid can also be changed this way. Be careful of the accounting dates when selecting the date for the reversal entry.  This process results in the original coding being reversed and your newly changed coding being accepted and posted through to Job Cost and General Ledger.

If you have Payroll costs that were inappropriately coded to the job, then it's more complicated than can be easily explained here.

You also have the option of using JC > Tasks > Direct Costs to enter negative amounts to the job, extra, cost code, category and reclassify to a General Ledger account.

I tried doing it in the Direct Costs screen with a negative to the job and a positive to the GL but it won't allow me to save because my "account totals are not in proof"

I tried using your last option and it wouldn't allow me to save... my totals don't balance when I put the negative to the job and a positive to the GL

Be sure to tab across the entire entry grid to see columns that may be hidden to the right. On the lines where you enter the negative job costs, you will notice that the GL accounts to the far right show the same accounts that were originally posted.  That's what you want.  When you are finished entering the negative job costs, on the next line of the grid, click the "GL Only Entry" button, and then enter the balancing amount, with the correct debit account you wish to use.

I think I just realized what I was doing wrong!  I was putting the GL account under credit account instead of debit.  Doh!  Thank you so much for your assistance. Super appreciate!
