ist it possible in SAC to use a generic dimension to show value differences between datapoints? I have a Chart which is based on a dimension in the format year.week (and year.week_txt) which is not a official date format in SAC. With a dimension in date format its no problem to use previous periods for difference calculation.
Maybe there is a possibility with a calculated dimensions? So I can reference to the previous Data and show the difference of both values in %.
Thank you very much
