A report often requires a single frame to display data from multiple business components. Each frame gets data from its report section, and each report section has one datastream. Each datastream is associated with a single business component through the report object definition. Normally, a data control cannot see beyond the bounds of its report section.
The solution is to create a data row, global in scope, that is visible to the entire report, not just to its report section. You do this by putting a variable on the report design component. It is then possible to populate the control with the proper data.
In Figure 13, a sample of the report displays quote master information at the top and provides a subreport in the middle containing the list of individual quote line items.
