Hi,
To use a BEx query, it means the data source must be BW.
And since BPC comes in 2 versions, i.e. NW and MS; if the data source is MS (i.e. SQL), then the only option left for mobile is to have a BO Universe layer between SQL and BPC, yes?
By the way, i'm wondering if the BEx query is created via 'Query Browser -> Add Query'?
Thanks,
