This overview will explain the parameters and how they will influence the creation of a Standard cost estimate.What is a Standard cost estimate?A material cost estimate used to calculate the standard price in the material master record. The cost estimate must be executed with a costing variant that updates the material master, and the cost estimate must be released. You can then use this Standard cost for the update of the Material Valuation, Variance calculation or Simultaneous costing etcGetting StartedYou should have already created the BoM, Routing, Overheads, Additive Costs etc..You can create a cost estimate for a finished/semi-finished good, the cost estimates are created bottom up i.e. the BoM is exploded and the bottom level of the BoM are costed first then rolled up to the next level and so on.When you first execute CK11N you will see the screen as per below:

Below are the fields to be inputted in the initial Screen:Materials:This is the finished or semi-finished Material that you want to costs.Plant: This is the Plant that the Material is located in.Costing Variant:Each Cost estimate is linked to a costing variant. The Costing variant controls most of the Parameters for the cost estimate. Standard costing variants are supplied but you can also create your own. Most common is PPC1 this is used for standard cost estimates. Transaction OKKN will bring you to the customising of the costing variant.Costing Version:Each Material/Plant cost estimate has a different costing version number. You can have many costing versions saved but you can only release one.Costing Lot size(optional):determines the batch size of materials you want to cost together. You can input the value in the initial screen of CK11N, if you leave this blank then the costing lot size will be taken from the Material Master.Transfer Control(optional): This controls how the System searches for existing cost estimates, this can help improve performance. The single-plant strategy prevents the assemblies in the production structure from being re-costed. With the cross-plant strategy,you control whether costing data forspeciallyprocured materialsis to be transferred from the other plant.Below are the parameters that have to be inputted in the Dates tab.

Costing Date From:is the date from which the standard cost estimate is valid from.Costing Date To: is the date from which the standard cost estimate is valid to.Qty Structure Date:Date with which thequantity structureis selected for the cost estimate with quantity structure.Valuation Date:Date on which the materials and activities in a cost estimate are valuated.The default dates can be customised in the costing variant. See transaction OKKN control tab date control.Below are the parameters that have to be inputted in the Qty Structure tab.Below are the parameters that have to be inputted in the QTY Struct tab.BOM:lists all assemblies and other components in the Material.Usage:the area in which the BoM will be used in, for example you can have a Production DBoM , Costing BoM.Alternative:a BoM can have an alternative BoM, for example there could be two BoM with different Materials in each of the BoM. Depending of the Materials available, you use a specific BoM to make the same finished Material.Task List Type: is the list of tasks that make up the Routing, these can be categorised into types.Group: two routings that have different production steps for one materialBelow is the results after CK11NYou can view which BoM and Routings are selected in the Qty Structure tab

In the top left on the Screen you can see the Costing Structure.In the bottom of the Screen you can see the itemization, this displays all the line items.

In the history tab you can see which user costed, released and marked the Cost Estimate

To view the Cost Component split, please go to the menu's on top the select costs -> Display Cost Components and you see the below:Then you will see a breakdown of the Cost components.To view the Costs select the 'cost' tab.

To view the error log, select the 'error log' icon in the right middle of the screen.

When you save the cost estimate you have the option of saving the error log or not.There are options on how to deal with the log in the Costing Variant (transaction OKKN) as mentioned below.
