In the customer deliveries grid, I would like to show an attribute of the linked sale order (and be able to search by this attribute).
But the customer delivery → sale order link is special, it goes via the « originId » / « originTypeSelect » combo, and adding a field this way :
<field name="origin.externalReference" />
will not work.
How do I do to access and show an attribute of the « origin » entity?
Thanks a lot!
