I would like to ask a question. In version 5.0 when making a purchase and before receiving stock, these could be edited (delivery notes) and modify the quantity, the storage, … in 5.4 does not leave me. He tries to open but does not open anything. Has it happened to you?
This is on purpose changes, see Issue 7823: Remove form mode on invoices, shipments on sale and purchase view - Tryton issue tracker
Normally those records (invoice, shipment) should be edited from a relate. But I think we are missing a relate for the moves there. They can still be edited from the “Inventory & Stock > Moves” entry.
