You are right, the change will affect the transfer prices to Interroll (Asia), but on the other hand these are your production costs. You cannot sell goods below your production costs. The impact on the transfer price might be a little bit mitigate as the material costs remain unchanged. The effective impact on the transfer price can only been calculated by you.
I would also not postpone the change until 2017. In any case you will have to face questions from the SU’s why there is an increase in the transfer price. So I think it is better to face them now. If then on a concrete case, you can show us that the increase of the transfer price of the final product is considerably higher, Corporate Finance will decide if partially reduce your rates.
In any case from 2017 you will have increased rates.
Concerning the missing rate of 3911TH10 I think that the problem is elsewhere, as also in 2015 there were no cost allocated to products reported (by the way in your screen shots you have for 2016 Version 0 and 4)
