As I have mentioned before, I recommend using the cost accounting module instead of using the "Statistic Transactions" journal type. Since statistic transactions journal type was once part of the "old" outdated cost accounting module and cannot be used anymore.
Please refer to https://technet.microsoft.com/en-us/library/aa585226.aspx and you notice even though Microsoft has not removed the old journal type there isn't any form that you can use this type of a journal as of version 2012.
Started from AX 4.0 There is no need to use a special journal. Starting from AX 4 you can simply have a zero value General Journal, so long as a Quantity is entered on the General tab. As a reminder you would need to add quantity field to be added to the journal by using personalized option.
