Refurbishment Order - Material cost update

Hi,

I am setting up Internal refurbishment orders. I have maintained new val type price as '1000' and 'Refurbished' price as 500. Moving average is maintained.

The order costs are 85$. I performed GR of refurbished stock with a value of '500'. Once the settlement is performed, the REFURBIHSED material price is updated as '85' with stock=1.

I was not sure why this happened even the order costs are 415 (500-85).

Appreciate your help. Thanks.
