Currently the data set is more useful than the workbook itself because of the multi join. As you can't export the workbook if the business want to make use of charts etc. they download the dataset to Excel and do all the analysis there. The biggest issue we find is the performance, it takes a lot longer to return data and the only suggested solution is to apply more filters...it's a YTD Sales list, we're 7 months into the year it's going to have a lot of data!
