PREPAY REFUND - PAYGL02 GL Interface missing combo codes for some liability lines.

I have had an issues the last two payrolls with the PAYGL02 GL Interface not creating combo codes for some of the liabilities. It looks like the issue is related to a PREPAY deduction refund. Any deduction or tax liabilities that are employer paid or covered by the Earnings on the check are fine the process creates the accounting lines as expected. However, when we run out of earnings, any employee paid deductions or taxes covered by the PREPAY refund show up on the accounting lines without a full combo code only the account.

We do this for our contract faculty in every summer and don't have an issue. This is an odd contract person who did not work January or February, the PREPAY balance was deducted last year and refunded on the first two checks to cover some of the benefits.
