• What is the cause and solution for SAP error message KQ451 - Strategy & including additive cost components not allowed ?

  The SAP error message KQ451, which states "Strategy & including additive cost components not allowed," typically occurs in the context of product costing or cost planning in SAP. This error indicates that there is an issue with the costing strategy being used, particularly when it involves additive cost components.
  Cause:
  
  
  Costing Strategy Misconfiguration: The error often arises when the costing strategy defined for a material or product does not support the inclusion of additive cost components. Additive costs are additional costs that can be added to the base cost of a product, such as overhead or specific surcharges.
  
  
  Cost Component Structure: The cost component structure may not be set up correctly to allow for additive costs. This could be due to missing configurations or incorrect settings in the cost component structure.
  
  
  Costing Variant Settings: The costing variant being used may not be configured to handle additive costs. Each costing variant has specific settings that determine how costs are calculated and what components are included.
  
  
  Solution:
  
  
  Review Costing Strategy: Check the costing strategy assigned to the material or product. Ensure that it is configured to allow for additive cost components. You may need to adjust the strategy or select a different one that supports additive costs.
  
  
  Check Cost Component Structure: Go to the cost component structure in the configuration settings and verify that it includes the necessary additive cost components. If not, you may need to modify the structure to include them.
  
  
  Adjust Costing Variant: Review the settings of the costing variant being used. Ensure that it is set up to include additive costs. You may need to create a new costing variant or modify the existing one to accommodate the required cost components.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for detailed guidance on configuring costing strategies, cost component structures, and costing variants.
  
  
  Testing: After making the necessary changes, perform a test run to ensure that the error is resolved and that the costing calculations are performed correctly.
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes such as CK11N (Create Cost Estimate) or CK40N (Change Cost Estimate) to review and adjust cost estimates.
  Configuration Path: The configuration for cost component structures can typically be found under the following path in the SAP IMG: 
  
  Controlling > Product Cost Controlling > Costing > Cost Component Structure.
  
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional insights into similar issues.
