Using filter@ merge fields causes the document generator to pause at runtime and prompt the user to make a selection before the generator continues.

If you want the user to select related objects or sub-object(s) from which data must be retrieved, use filter@ merge fields. The Related and Sub-objects Available Through @filter or @loop table provides a list of related objects and sub-objects that the user can select for including data in the generated document.

When you use filter@ to define merge fields, you specify which related object records or sub-objects the user can select while generating the document. Data is then pulled into the document from the user-selected related records or sub-objects.

You can also nest a filter within another filter. For example, if you need the user to select a child project, and then select an assignee, you would nest one set of filter@ merge fields within another.

Note: filter@ corresponds to the Document Generator tag tc:filter.
