When you have a derived item list, you can add, delete and change quantity and data on the occurrences. The changes occurrences will be colored orange to indicate deviations from the template values. When working with derived item lists, you should be aware of these the following rules;:
- Adding an item to the template will add to all derived lists as well.
- Removing the occurrence from the template will remove it from all item lists, also in derived item lists. So deleting the two chairs in the template will delete the chair in this room too.
- Derived occurrences will no longer be updated from the template. If you change the quantity in the room like in this example, updating the priority on the template will not change the priority for this occurrence.
