Contract items are the priced lines of a contract - spare parts, services and transport costs the supplier has agreed to deliver. They are managed per contract: select an entry in the contract tree and the items assigned to exactly that entry are shown on the **Data** tab.

Items are sorted by their item number in natural order, so `2` comes before `10` just as in the supplier's price list.

## Adding and changing items

The functions are available in the ribbon and in the item list:

- **New Item** creates an item in the selected contract.
- **Edit** opens the selected item. A double-click on a row in the item list does the same.
- **Delete** removes the selected item after a confirmation.

The item editor contains the following fields:

| Field | Meaning |
|---|---|
| Name | Description of the item as agreed in the contract |
| Type | Additional type or brand information |
| Item No. | The position number of the item within the contract |
| Makers Ref. | The manufacturer's part number |
| Internal No. | Your own reference for the item |
| Unit | Unit of the agreed price, for example `pcs`, `hour` or `set` |
| Value / Currency | The agreed unit price and its currency |
| Description | Free text with further details |

## Item types

Contract items are distinguished by their type, because a contract usually covers more than spare parts alone:

- **Spare part** - a physical article delivered under the contract.
- **Service** - work performed by the supplier, for example service hours on board or in the workshop.
- **Transport** - travel and transport costs agreed with the supplier.
