Here we are setting the 'Report_Title' Mapping Key to the "Product Line Report"
There are three different types of mappings. A label mapping is simply a straight text replacement used only for display purposes. An item or detail mapping is used to map a column which will appear in the items section of the report. A group mapping is used to setup report groups. When the report groups are mapped, the wizard will automatically update the report to use the desired columns as groups.
