I had issues with getting ReportBuilder to work with vlookups as reference cells for data requests. ClientCare explained it as "Vlooup is not a part of server side element, therefore, it won't be included when it's being refreshed from our server to generate the data to deliver." He suggested to suggest it here so it can be added into the next ReportBuilder upgrade. Having the vlookup will help make ReportBuilder-based files easier to manage and dynamic for scheduling.
