KN036 - Details

• 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
