If you generated mm document with movement type 301(plat to plant),
price variances from the sender plant’s material were rolled to the receiver plant’s material during the multi-level costing.
As a result, Not allocated was not occurred.
In this case, If Not allocated was occurred as big amount, I don’t know how to fix it.
If you generated mm document with movement type 309(material to material),
price variances from the sender plant’s material were not rolled to the receiver plant’s material during the multi-level costing.
As a result, Not allocated was occurred
In this case, you can solve the problem by note 167722.
