How to Create an Adjustment against a Completed Bill

The system allows you to create an adjustment against the previous completed bills of an account. When you create an adjustment against the previous completed bill, the previous bill balance is affected, but the adjustment is presented on the next bill of the account. When the next bill is completed, the presentment bill ID is stamped on the frozen adjustment FT.

You can create adjustments against the previous bill when the Print By Default check box is selected on the adjustment type. While creating and freezing an adjustment which is created against the previous bill, the system stamps the match event ID of the previous bill on the adjustment FT. This happens when you create an algorithm of the C1-GTPRBLME algorithm type and attach it to the Adjustment Freeze algorithm spot on the adjustment type. This algorithm checks whether there is any unbalanced match event on the previous bill. If the unbalanced match event exists on the previous bill, the match event ID is stamped on the adjustment FT. However, if the unbalanced match event does not exist on the previous bill, the match event ID is not stamped on the adjustment FT.

At times, as a result of credit adjustments created against a previous completed bill, the previous completed bill balance may change from debit to credit. If the previous bill amount is in credit, the system must transfer the credit on the overpayment contract of the account by creating the transfer adjustment. This happens when you create an algorithm of the C1-BLCRXFR algorithm type and attach it to the Adjustment Post Freeze algorithm spot on the adjustment type.

If the overpayment contract is not available on the account, the system first creates the overpayment contract on the account and then creates the transfer adjustment. If the match event ID is available on the adjustment FT, the system stamps the match event ID on the bill side of the transfer adjustment. However, if the match event ID is not available on the adjustment FT, the system creates the match event and stamps the match event ID on all FTs of the previous bill and on the bill side of the transfer adjustment.
