StephD we ended up creating a template using XFSet. Our users wanted to be able to link their forecasting models to the OneStream upload template using SUMIFS formulas. All of the XFSet logic is hidden/locked from them. All they have to do is work in their models and when ready to submit, login to the excel add-in and click submit sheet. Another reason we went with XFSet is the issue when rows shift in a cube view, such as a new GL account added during the year, it can easily break an end user's links to other tabs in their workbook.
