I am getting an error "unknown service id" when trying to view the data in JOIN or UNION node in the graphical view or sql view i created in SAP DWC. I tried to use the local table created and populated using data flow in DWC and i tried using the table created using real time replication in DWC as well. Both of them showing same error .
But i am able to use data viewer if the view is not having any join and its having only one table in it.
i am using 90 days trial account to use DWC. Please let me know how to check the details of this error and resolve it.
