I love wewesthemenace answer! Up-voted and have saved it for future reference. Here is another suggestion. Use this code in SQL command from Crystal. Left outer join to your table sales. Its long. Its tedious. But its easier to understand if you aren't an SQL expert which describes me pretty well :) If you figured out his answer and it works then disregard this solution.

Note: the from clause isn't serving any function except to satisfy the requirement of having a from clause in an SQL statement like this. If tblSales is a large table consider using one from your database which has less data and still left outer join to tblSales.
