John, the deduction by department worked ONLY allows you to override the ACCRUAL account, not the expense account. I don't think you are doing anything wrong if you are trying to change the expense account. In Sage's infinite wisdom, they used the wrong side of the entry (accrual) instead of the expense side. I am sure there is a suggestion on the idea web site from many moons ago. The only reaction from Sage is that WE are the ones ""mooned"". There is a thread from earlier in the month that Eric Anderson started on this very subject. To change the expense side, you will have to get the enhancement, do a JE at month end or get creative as I suggest on the post.
