I am trying to create a crosstab report in crystal that will calculate the percentage between summed values that are grouped/totaled by month, qtr and year. If I use the weighted average feature the percentage value by month is close but not exact. The values calculated for qtr and year are completely incorrect. I have done this exact calculation in an OWC pivot table using the "calculated totals" feature and the result are exactly what I am looking for. Only problem with the OWC Pivot Table is that the summed values are aligned horizontally and I need them vertically. The Crystal Crosstab control gives me the presentation exactly as I need but the percentage calculations is an issue. Any suggestions. I have crystal xi with a sql2000 backend.
