SuiteAnalytics Workbook question: I have a category (Pandas) to which several items are associated with (e.g. Pink Panda, Grey Panda, etc.). In the Transaction Detail Dataset, there is a calculation of the Gross Margin in percentage (%) for each of these items based on their sales. In the Workbook, I want to aggregate this number to total sales for the Panda category. But all I can do is SUM or AVERAGE the line-level values, i.e. a GM 20% and a GM 25% becomes an aggregated margin of 45% (SUM) or 22.5% (AVERAGE), but evidently neither provides an accurate number to what I am looking for. Is there no way to do this % calculation in SuiteAnalytics Workbooks?
