Saving Material Cost Estimates 
Use
When you create a cost estimate, you always link it to a costing variant. You can specify the following in Customizing for the costing variant:
That the costing results can be saved
That system messages can be saved in a log
Whether (in addition to the cost component split) the itemization and the log are always or optionally saved
Note
If saving the costing results has been allowed for in the costing variant, the cost component split is always saved. You cannot save the cost component split on an optional basis.
( )
The itemization is required to carry out reference costing , variance calculation, scrap valuation, and the calculation of work in process (WIP) for target costs.
( )
The cost element itemization cannot be saved. Cost element itemizations are required for cost element reports in the Information System. However, this information can be extracted from the itemization.
If you use your own programs or reports to evaluate cost element itemizations, you must use the function module CK11_ITEMIZATION_TO_COSX_CONV, which creates the cost element itemization from the itemization.
Features
When you save a material cost estimate , a dialog box appears in which you can specify which costing results you want to save.
Note
You can suppress this dialog box is suppressed if the indicator Defaults can be changed by user has not been turned on in the costing variant in Customizing. In this case, the system automatically saves the costing results that were flagged to be saved in the costing variant.
When you create a costing run , you enter update parameters that specify which costing results you want to save. For more information, see Creating the Costing Run .
Activities
In Customizing for Product Cost Planning , check the settings of the following parameters for saving the costing results:
Costing V ariant
To be able to save the costing results , turn on the indicator Saving allowed .
To save system messages in a log , set the relevant indicator for Error management .
If, in addition to the cost component split , you want to save the itemization and the log (either always or when desired), set the relevant indicator.
If you want to these settings to be changeable when the user saves the cost estimate, set the indicator Defaults can be changed by user .
Costing Type
You use the costing type to determine the field in the material master record in which the results of the cost estimate are updated (such as the standard price , tax price , or commercial price field), and to determine the valuation view to be costed.
Date Control
Define or check the date control . The system uses the date control ID to propose the validity period of the cost estimate. If you intend to perform the following business transactions, make sure the cost estimate is valid in the periods in which you carry out the transactions:
Variance calculation
Scrap calculation
Work in process calculation
Cost Component Structure
Assign a cost component structure to the costing variant. The costing variant specifies a cost component structure containing the complete control parameters for the assignment of costs to cost components .
