I have a crosstab that has products along the rows and dates as cloumns in the total column i only want to display the value of the Min and Max dates e.g
The quickest solution would be to create the crosstab,
right click and place a min and a max calculation on the crosstab - so you get 2 new columns at the right hand side of the crosstab.
Then: View > Outline > Fold the Xtab horizontally … this will hide the body of the Xtab and leave just the min / max columns.
When I troubleshoot, I find it easier to create a new report with just those that I am dealing with. You can create your formulas there, or have BO do that. Once you have the values you want, turn them into Variables, and make sure that you set your Context Sensitivity on.
