In view of 2017 you need to execute a new calculation costing run (CK40N). If you are familiar with it fine. Then you need just to do it and confirm it to me, that you have done it for 2017.
If you are less familiar and would like that Vojislav helps you, them please fix with him a telco so that you can go through the different steps. As you might have to clarify things with your production, I would suggest to do it as soon as you have finished your month-end closing work for November.
In any case, please let me know until Friday, 9th December 2016 what you intend to do.
