How do I go around the error message: Cannot blend the secondary data source because one or more fields use an unsupported aggregation? I'm trying to blend two different data sources: Opportunities and Products. I use Opportunities as the primary source and ID to relate the two data sets. I only receive this error when I use a field from the Products set as a filter.
Hi Chris, can you share a packaged workbook for us to see? Otherwise, it's a bit hard to diagnose the issue.
