The GL entries generated for the corrections I processed in Altru have zero dollar amounts. I followed the steps in the second option to refund a back office payment, and when I ran my Post to GL process the GL Distributions tab shows only a zero dollar payment instead of the original payment and a reversal for the refund.
If you would like the General Ledger to show the original back office payment and the reversal for the refund, you will need to post the original payment to the General Ledger prior to refunding. Once the original payment has been posted refer back to the second option in the steps to refund the back office payment. After completing the refund, run the Post to GL process again. The GL Distributions tab should now show the original payment and the reversal.
