How do I add a part from a repair file?

From the ‘Repair file n°XXXX’ tab

1. Click on the "Repair" category
2. Click on the empty "Reference" field in the list of parts
3. Search for the part if it is in your repository by clicking on "Search". If you wish to add a reference without entering it in your repository, you can enter the fields "References", "Quantity" and "Management" and then click on "Add part". This will add the item to the file as a "free" item. This item cannot be ordered, as it will not be attached to any stock.
4. Click on ‘Preparation of orders’
5. Find the part added to the intervention file in the ‘Preparation of orders’.
