Report Designer has a Preview function for running prints. The Preview function allows you to verify a report's layout while you are designing it.

To preview a report, your browser must allow pop-ups from (cloud Reporting) or from your domain (on-premises Reporting).

You do not have to save the report before you preview it. The Preview function shows the current state of the layout.

When you preview a report created with the Layer Report Wizard, the Preview prompts you to enter the feature IDs to use as inputs. You can configure default values for the FeatureIds parameter so you don't have to re-enter the feature IDs every time you preview the report.
