Can an Xcelsius dashboard show data from more than one BW source (example: 2 infoCubes) at once?
Yes, you can have multiple connections (BEx queries) to a single BW server. Under the Data Manager, you define multiple SAP Netweaver BI connections against e.g multiple MDX queries, however as mentioned, currently there is only one SAP server connection object per dashboard – so all the defined connections will be to one SAP server (BW logical system).
