Manufacturing costs for purchase part

Hello All,

My customer has a problem because he sometimes manufacture purchase parts but the manufacturing cost is not considered to valuate parts : buckets ‘200’ Labor and 300 ‘Machine are missing (even missing on the shop order itself)

Settings of inventory part:

part type = puchase 

Inventory valuation method = Weighted Average

Does someone knows if it’s normal in IFS? Is there any possibility to consider these cost buckets to valuate properly the parts received into stock

Thanks in advance :)
