• What is the cause and solution for SAP error message KN036 - Cost estimates have different cost component structures ?

  The SAP error message KN036, which states "Cost estimates have different cost component structures," typically occurs when there is a mismatch in the cost component structures of the cost estimates being compared or used in a transaction. This can happen in various scenarios, such as when trying to transfer or compare cost estimates for materials or when performing certain calculations in the system.
  Cause:
  
  Different Cost Component Structures: The primary cause of this error is that the cost estimates involved have different cost component structures. This means that the way costs are categorized (e.g., material costs, labor costs, overhead costs) differs between the cost estimates.
  Changes in Costing Variants: If there have been changes to the costing variants or the configuration of cost components in the system, it can lead to inconsistencies.
  Different Valuation Areas: If the cost estimates belong to different valuation areas or plants, this can also lead to discrepancies in cost component structures.
  
  Solution:
  
  Check Cost Component Structures: Review the cost component structures of the cost estimates involved. You can do this by navigating to the cost estimate in question and checking the cost component view.
  Standardize Cost Component Structures: Ensure that all cost estimates that need to be compared or used together have the same cost component structure. This may involve adjusting the configuration in the costing variant or the cost component structure settings.
  Use the Same Valuation Area: If applicable, ensure that the cost estimates are from the same valuation area or plant to avoid discrepancies.
  Recreate Cost Estimates: If necessary, recreate the cost estimates using the same costing variant and ensure that the cost component structure is consistent.
  Consult Documentation: Refer to SAP documentation or consult with your SAP support team for specific guidance on how to align cost component structures.
  
  Related Information:
  
  Cost Component Structure Configuration: Understanding how to configure cost component structures in SAP is crucial. This can be done in the configuration settings under the controlling module (CO).
  Costing Variants: Familiarize yourself with the costing variants and how they affect cost estimates. Each costing variant can have its own settings for cost components.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Transaction Codes: Use transaction codes like CK11N (Create Cost Estimate) or CK40N (Change Cost Estimate) to analyze and modify cost estimates.
  
  By following these steps, you should be able to resolve the KN036 error and ensure that your cost estimates are consistent and compatible within the SAP system.
