Hello reitradu
Sure, you can generate a report of all your items in the inventory.
When on the Resources > School Inventory program, click on the "All items" link.
Then, if you want a PDF, click the "Print" button.
If you want to export the list to Excel, click the download button / icon above the list (just as with any list in RosarioSIS).
The same can be done with inventory snapshots.
