Dear Gurjar,
In overview sub tab we can find both manpower costs and material cost and services cost.
In key figures tab only actual cost will appear ( That means once the time confirmation is done it will show in this tab.
In cost tab also we have a same advantage as that of Overview tab.
In Quantities tab we are defined some valuation categories in the system to maintain several valuation types that cost will be displayed in this tab.
Regards,
Harsha.
