According BOM of some assembly part, material just consume only component part 1ea. However after executing cost estimate (CK11N transaction). The result got that component 2ea.

The error might be caused by some value in material master. If assembly material master is updated the component scrap in percent field on MRP4 view. This makes the cost estimate increased.

Component scrap in percent value is also used in material requirement planning (MRP) to determine the quantities of component required. When exploding the bill of material (BOM), the SAP system will increase the required quantities of the components by calculated scrap quantity
