• What is the cause and solution for SAP error message CKCC126 - Select additive costs only ?

  The SAP error message CKCC126 "Select additive costs only" typically occurs in the context of cost planning or cost calculation in SAP, particularly when dealing with cost components in the Controlling (CO) module. This error indicates that the system expects only additive costs to be selected for a particular operation or calculation, but the selection includes non-additive costs.
  Cause:
  
  Incorrect Cost Component Selection: The error usually arises when the user selects cost components that are not classified as additive. Additive costs are those that can be summed up directly, such as materials and labor, while non-additive costs may include overheads or fixed costs that do not behave in a linear manner.
  Configuration Issues: There may be issues with the configuration of cost components in the system, where the system does not recognize certain costs as additive.
  Data Entry Errors: Users may inadvertently select the wrong cost components during data entry or planning activities.
  
  Solution:
  
  Review Cost Component Selection: Check the cost components you have selected in your planning or calculation. Ensure that you are only selecting those that are classified as additive.
  Consult Cost Component Structure: Go to the configuration settings in SAP (Transaction code: OKTZ) to review the cost component structure. Ensure that the components you are trying to use are set up correctly as additive.
  Adjust Planning Layout: If you are using a planning layout, ensure that it is configured to only allow additive costs to be selected.
  Training and Documentation: If users are frequently encountering this error, consider providing additional training or documentation on how to select the correct cost components.
  
  Related Information:
  
  Cost Component Structure: Understanding how cost components are structured in SAP can help in identifying which costs are additive and which are not.
  SAP Notes: Check for any relevant SAP Notes that may address this error or provide additional guidance on cost component configuration.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CK11N (Create Cost Estimate) and CK40N (Cost Planning) to navigate through cost planning processes effectively.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a consultant who specializes in SAP Controlling for further assistance.
