Is it possible to include more than one data source in a single request? For instance, I would like to execute the Guid data source to change the tracking ID, and I need Excel to read the values
richie is correct. You can obtain values from several data sources and it does work. richie's point around ensuring the data source nesting is correctly wired up is the biggest factor.
richie also makes an excellent point around using the UUID generator. Might save you some effort.
