• What is the cause and solution for SAP error message KK178 - Mixed cost estimate not allowed as reference -> no copy ?

  The SAP error message KK178 ("Mixed cost estimate not allowed as reference -> no copy") typically occurs when you are trying to create a cost estimate in SAP that references another cost estimate, but the reference cost estimate is a mixed cost estimate. Mixed cost estimates are those that contain both variable and fixed costs, and SAP has certain restrictions on how these can be used as references for new cost estimates.
  Cause:
  
  Mixed Cost Estimate: The primary cause of this error is that the cost estimate you are trying to use as a reference is classified as a mixed cost estimate. SAP does not allow mixed cost estimates to be used as a reference for creating new cost estimates.
  Cost Estimate Type: The type of cost estimate you are trying to create may not be compatible with the mixed cost estimate you are referencing.
  Configuration Settings: There may be specific configuration settings in your SAP system that restrict the use of mixed cost estimates.
  
  Solution:
  
  Use a Different Reference: Instead of using the mixed cost estimate as a reference, try to use a standard cost estimate or a cost estimate that is not mixed. This will allow you to create a new cost estimate without encountering the error.
  Create a New Cost Estimate: If you need to create a new cost estimate, consider creating it from scratch rather than referencing an existing mixed cost estimate.
  Check Configuration: Review the configuration settings in your SAP system related to cost estimates. Ensure that the settings align with your business processes and requirements.
  Consult Documentation: Refer to SAP documentation or help resources for more detailed information on cost estimate types and their restrictions.
  
  Related Information:
  
  Cost Estimate Types: Familiarize yourself with the different types of cost estimates in SAP, such as standard cost estimates, variable cost estimates, and mixed cost estimates.
  Transaction Codes: Common transaction codes related to cost estimates include CK11N (Create Cost Estimate with Reference) and CK40N (Change Cost Estimate).
  SAP Notes: Check for any relevant SAP Notes that may address this issue or provide additional guidance on handling mixed cost estimates.
  User Roles and Authorizations: Ensure that you have the necessary authorizations to create or modify cost estimates in the system.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in controlling (CO) and cost management.
