I am trying to build a data-driven subscription in SSRS (In SharePoint integrated mode, but I believe that's irrelevant). The rsds file I am running against has a certain parameter that is a hard-coded list of about 20 values. In the subscription, I need to run the report and generate a separate Excel file for each of the 20 values. Where do I assign those those values from within the subscription definition? I can specify a query but don't see where to point to the parameter list that is hard-coded inside the report file. Can't I just point to the list and have this run 20 different files automatically or do I need a separate subscription for each value?
