Hello I am trying to generate an order fullfilment app. so I have customers, orders and deliveries, one order can have multiple deliveries. so I need to add a new delivery, and then the items delivered from the order. I am having trouble filtering the order detail.
the delivery form goes, select cliente, select order, and then the items from the order but the dropdown shows all the orders.
Ok I figure it out, I created a virtual column that has the value that I need to filter and then I use a dropdown using a select xpresion on the valid_if field
