You can use cost planning with cost elements (detail planning) if you have exact information. This is mostly only possible in advanced projects or orders.

Detail planning takes place on an annual basis and includes the planning by cost element of:

• Primary costs
• Activity input
  Planning activity input is the quantity-based planning of secondary cost elements on a project that uses activity from a sender cost center.
• Statistical key figures
  You can plan statistical variables, such as, the number of employees.

You need to save the values from the detail planning separately.
