I have solved this issue by changing the procure method of the transfer and deleting the origin movement of it.

This happens when a transfer links to other transfers created through procurement rules, if any of this created transfer is cancelled the first transfer can't find what needs through it procurement method, in this case MTO.

I don't know how to change it in odoo but i've made the changes in the db:

do $$
declare move int:=1156309; /* This is the id of the transfer with the issue */
begin
delete from stock_move_move_rel where move_dest_id= move;
update stock_move set procure_method='make_to_stock' where id= move;
end $$

The strange thing is that in the products "Forecasted" has been updated with the quantity in the order ... but they are not reserved.
