In this scenario, the list object will need to be associated to a new master query which consists of only the Product line data item with no summary filter.
在这个场景中，列表对象需要关联到一个新的主查询，该查询只包含没有摘要过滤器的Productline数据项。
By using the for clause in the after-aggregation detail filter on a non-projected data item, the underlying query automatically projects and groups the item as the outer most column of the list.
通过在一个未投射的数据项上的after - aggregation细节过滤器中使用for子句，底层查询会自动将该项目投射并分组为列表的最外层列。
Although the Product line has been replaced with the Product type query item, the summary filter is still in place and scoped on a now non-projected data item "Product line".
尽管Productline现在已经替换为Producttype查询项目，但摘要过滤器仍然就位，并以一个现在没有投射的数据项目“Product line”为范围。
In the Data Type Selection dialog, shown in Figure 16, specify Loan in the filter field to filter by business items in the sample Loan project, and select the appropriate business item.
在DataTypeSelection对话框(如图16所示)中，在过滤字段中指定Loan，按照样例贷款项目中的业务项目过滤，然后选择适当的业务项目。
