Hi Sadegh,
1 & 2. You have to provide a cost centre, which you have used for material consumption posting. or you can use purchasing/ inventory management cost centre
3. If you define 10% on material consumption means your material overheads would be 10% on material consumption. If you want to charge the over head on different components with various ratesi.e. material consumptin, salary, SFG etc. then you have to create a base for each component. For this base you have to assign cost elements or cost element group. Later you have to define various overhead for each component.
For example . You have to define the costing sheet based on your requirement.
Row - Base - From row - To Row - Credit
10 - Material consumption
20 - Material overhead(10%) 10 10 Purchase CC
30 Salary
40 Salary overheads (15%) 30 30 HR CC
50 SFG Consumption
60 SFG overhead (5%) 50 50 SFG CC
Hope you are clear know.

Mukthar
