[fbcideas_migusr]

Is there a PowerBI sample available with R transform script running in SQL Server execution context? I am getting following error: Error in .rxEnsureOdbcCredentials(connectionString, server, databaseName, : Trusted_Connection or User must be specified either in the connection string with the uid keyword or as a named parameter. Calls: rxSetComputeContext ... initialize -> initialize -> .local -> .rxEnsureOdbcCredentials Execution halted Please suggest.
