It depends on the ship-to data of your transfer order and the extend to which KBs are installed. Given the message you received, you do miss at least KB 1843196. (And maybe KB 1857915).
GL Account are only allowed for manual orders.
For transfer manual orders, it is (initially) only allowed to have an GL code when no stock movement takes place. Example:
- the ship-to warehouse should have been a WIP warehouse.
- item transfer into a floor stock item.
With later KBs also transfers to normal warehouses may often have a GL Account.
