Step 4: Specify a data source in a report
In a report definition, the data source of a column variable or row variable is the name of the source database variable from which data will be retrieved for the report. You also specify the label that will identify the variable in the report.
Note:
If a row variable's underlying column has the same name as any column in an analysis variable's table, then a SQL inner join of the same-named columns occurs in addition to the usual join on report ID.Parent topic: Create report definitions
