In a page report that is created using query resources, when a data component is inserted into another data component, you can use data container link to set up a relationship between the parent and child data components.
A data container link includes:
Assume that you have created a banded object showing the customer information. Then, you insert a table into the detail panel of the banded object, which displays the order information. Now you want to set up some link conditions between these two components, so that when you view the report, a table will be generated according to the ID of the customer as follows:
To achieve this, select the table and right-click it. On the shortcut menu, click Data Container Link, then specify the settings as required in the Link Data Container dialog.
Generally, a data container link functions the same as a subreport link. The only difference is that you do not need to specify a specific component that is linked with the parent data component, since you have selected the child as the target of the link. For additional information about how to set up the link, refer to Subreports.
