Creating Unit Cost Estimates with Reference 
When you create a unit cost estimate, you have the option of copying the costing data from existing cost estimates. The object for which you are creating the unit cost estimate determines which existing cost estimates you can access.
For example, if you create a unit cost estimate for a sales document, you can copy the costing data from a base planning object or from another sales document.
Object for unit cost estimate | Cost estimates that can be accessed |
|---|---|
Base planning object | Base planning object |
Cost object ID | Base planning object or other cost object ID |
Production order | Base planning object, material |
Sales document | Base planning object or other sales document |
Work breakdown structure (WBS) element | Base planning object or other WBS element |
Internal order | Base planning object or other internal order |
Material | Material |
Additive costs | Material |
