I am grouping data by date in half-year sections.
If a certain half-year contains no records it is left out.
The situation is this: Every 6 months x percent is added to the unpaid amount on an invoice i.e. a type of interest. All payments a customer makes toward an invoice in a 6 month period are displayed. At the end of the period the x percent is added to the unpaid amount. BUT when the customer makes no payments during a period the period does not show up in the report, and the x percent is NOT added. How do I make all 6 month periods between two dates (the invoice date and the current date, which is not Now but a date field) show up so I can calculate the charge?
