Credit memos are not technically deleted from the system until the next Daily Sales Register Update. Until then, the header status changes to Deleted and the system removes all line items. This procedure enables the system to keep an audit trail of all the credit memo numbers used.
To delete a credit memo before the header is complete:
Press F4 to back up to the Customer field.
To delete a credit memo after the header is complete:
With the document open on screen, click File>Delete Document from the menu.
From the Delete drop down list, click YES-Delete.
