Write-Off AR Entry

I am trying to create Write-Off entries by using the Maintenance Worksheet.  The isssue I am having is that I have defined the account and chartfield string for the W/O offset on the Automatic Entry Type Accounting Template.  However, when the AR entry is created the W/O goes to the correct account but not the defined chardtfield string (fund, budget unit, etc).  It goes to the budget unit that was originally charged.  How do I get the W/O to go to what I have defined?
