To edit a purchase order in VGM, follow these steps:
Navigate to 'Parts / Tyres > Purchase Orders'.
Select the purchase order you want to edit from the top grid.
Click on 'Edit' in the top toolbar. Alternatively, you can double-click the row to load the edit window.
In the edit window, you can make changes to the purchase order as needed.
Note: If the purchase order has already been sent to GroupTyre (MIDaS), you will only be able to edit the reference.
