For equipment with a 'Purchase' origin, the first pane contains information about its receipt, its supplier, the relevant purchase order, etcetera. These details are updated at the time you process the equipment receipt.
If the equipment originates from the warehouse, the second pane shows the number of hours the equipment was used and how many pieces were produced using the equipment. This information is retrieved from the processed hour lines.
The last pane shows whether the equipment was issued from the warehouse and whether its return has already been registered.
