Once a delivery note has been approved, you cannot change it, but you can create a new delivery note with the same information and animals that contains the correct information.
Find the approved delivery note. Go to "Breeding" - Customer/Distributor". Click on the customer and select "Deliveries" in the top right.
Open the delivery note with all added animals by double-clicking on "Total Quantity".
Copy all the ID numbers that are on the delivery by selecting all the ID numbers and clicking "Ctrl" + "C" on your keyboard.
These can optionally be copied in an excel sheet to save the copy.
Go to "Delivery Agreement" and create a new delivery agreement with the same information. Then click "Create delivery note".
On the new delivery note, you can paste the copied ID numbers by clicking "Ctrl" + "V" on your keyboard in the ID column.
A message about the animal to be moved to this delivery pops up for each animal. Here, hold down the "Enter" button on your keyboard until the messages disappear.
Now you can make your desired corrections to the new delivery note. When you're done, you can click "Approve Delivery Note".
The delivery with the errors will still be visible in the list, but it is possible to send the other new delivery note. Click on the previous delivery and click "Delete". A message with "Cancel delivery?" will appear, where you click "Yes" to cancel it.
Switch between 2 windows, for example. click on "Delivery note" and then on "Deliveries" again. Now the cancelled delivery is red and it says "Delivery cancelled" in the "Remark" column.
