If there are defined some reports for the schema, you supposed to see a menu button in the schema.
If you want to create a report, please go to this chapter.
When you select print button, you will see a page with all of the reports connected to the schema. In case there is only one report, of course you don't see any list and this one is selected ☺
After you select a report, you can see a filer for this report. After you make your choice, you can preview the report by clicking the button.
The rest is quite clear. There is no point to explain, what print or save button does.
If the report definition supports it, you can print only selected rows from a grid. Or prefill the filter from a grid filter.
