In certain situations, a contract may show an amount in the Contract Delivery tab which is labeled as "unused". There are three ways in which unused amounts may appear in a contract:
1. Manually set an unused amount using the edit function on the Delivery tab of a contract
A user with edit rights may edit the Contract Delivery tab and enter an unused amount on a specific deliveryline.
2. Delete a reservation
Deleting a reservation will put the amount back to unused in a contract delivery line.
3. The last delivery on a contract with tolerance does not match with expected delivery amount
If the execution quantities are entered in the Execution tab of a Delivery and the current delivery line is clearly the last one (there are no reserved quantities and the remaining balance is positive and within tolerance, a check box for "Delivery complete" is shown under the Balance. This is checked by default. Leave it ticked to have the remaining positive balance marked as Unused.
