my report currently looks like this
customer - delivery due date - ship date - ship qty
abc co - 5/21/13 -5/21/13 - 1
I have a parameter in the report that uses the ship date field to enter a date range, it works fine except now my boss wants me to list customers with delivery due dates that are within the date range entered even if they did not ship, so the report would look like this:
customer - delivery due date - ship date - ship qty
abc co - 5/21/13 -5/21/13 - 1
xyz co - 5/21/3 - 0 - 0
