Hi Seung Hyun,
I think it depends on the sample quantity, whether it is a fixed quantity or it depends to the raw material quantity or requirement from the orders. If it is not fixed, then you can use scrap percentage as suggested by Vivek.
If it is fixed quantity, then there are several alternatives to follow:
- Include the sample quantity to your safety stock
- Create another material number to distinguish the sample from the original raw material number and include it in the BOM
