I have a table that displays a set of fields from the current record, and also a few fields from records linked to the master record. Enabling inline editing lets me edit the fields of the current record, but it still does not allow editing fields of linked records.
Designing around this limitation is clunky at best.
Records in our "orders" object are linked to records in our "kits" object. Our warehouse order fulfillment team needs to pick and pack for each order. At the end, they need to update a field in the Kits record attached to the Orders record. A simple inline-edit of the table that shows all the current orders would be the fastest way to accomplish this, but inline editing does not allow us to edit the field in the linked Kit record.
