General Data 
Use
The costing view for the material contains the following general information:
Base unit of measure
Unit of measure in which the stocks of the material are managed.
With quantity structure indicator
This determines:
Whether the material is usually costed using material costing either with or without a quantity structure
Whether the system searches for existing material cost estimates with or without quantity structure when costing data is being transferred (see also: Transfer of Existing Costing Data )
Material origin indicator
Determines whether the material number is updated in addition to the cost element.
No costing indicator
Origin group
Used to separate materials whose costs are updated under the same cost element for cost accounting purposes.
If you enter origin groups in the relevant material master records, you can calculate overhead surcharges and production variances for each cost element/origin, for example. You cannot analyze overhead surcharges at origin group level in the unit cost estimate.
Overhead group
The overhead group is used when calculating overhead for a group of materials which have the same conditions. You assign the overhead group to an overhead key in Customizing for Product Cost Planning.
You control the calculation of overhead via a costing sheet. When you create a costing sheet, you must ensure that it contains the corresponding overhead key.
Variance key
The variance key contains control parameters for the variance calculation. When you create an order for the production of the material, the system enters the variance key you specified here in the order master data.
Plant-specific material status
Restricts the use of the material and determines the functions for which a warning or error message is issued. You define whether the material status allows material costing in Customizing for Logistics General or Product Cost Planning .
