I want to group on a "weekly" basis in a crosstab. I will have two parameters (start date of the qtr and an end date of the qtr). The word "weekly" is in quotations since sometimes the last week of the quarter will contain more than 5 business days. This is due to the fact that each quarter is divided into 13 weeks. (e.g., the last week of Q1 2003 had 6 business days, the last week of Q2 2003 will have 6 business days, the last week of Q3 2003 will have business 7 days, and the last week of Q4 2003 will have 8 business days.) Is this grouping possible in Crystal 6.0?
