Template Reporting for all records in a map layer - is a selection set required

Hi,

In process of evaluating geocortex so relatively new when it comes to its funcationality & capabilities.

This query is as much related to the ADF viewer, but my immediate interest revolves around the js rest api for now & reporting capabilties.

If you have a map layer which you want to run a report on for all records, is it necessary to perform a selection?  Is there a suggested approach to this scenario? Can the DataTableName property be pre-defined so that the report is always predefined for the map layer in question?
