Hi Faisal,
Below are my observations,
1. It doesn't seems that you have did GR by IW8W for this Order
2. If Split valuation is active & maintained for material then maintain the same in Ref Order.
Standard Refurbishment process is,
Create Refurbishment Order -> Reserve damage piece of Material/Equip -> Issue damage piece against Refurbishment Order along with required Spares to carry out repair process -> Goods Receipt with IW8W for repaired Material/Equipment with Val type-Refurbished ->Order Confirmation->Good Posting(GI) ->TECO -> Order Settlement(KO88) -> Order Closure
Thanks.
Amol
