• What is the cause and solution for SAP error message KPN078 - Costings have already been maintained for this project using overall plg ?

  The SAP error message KPN078 indicates that costings have already been maintained for a project using overall planning (overall plg). This typically occurs in the context of project system (PS) or controlling (CO) modules when you attempt to perform an action that conflicts with existing costings.
  Cause:
  
  Existing Costings: The primary cause of this error is that cost estimates or cost planning have already been executed for the project in question. This means that the system has already recorded cost data that cannot be overwritten or modified without specific actions.
  Project Status: The project may be in a status that does not allow for further cost planning or modifications.
  Locking Mechanism: The project might be locked for changes due to various reasons, such as being in a closed period or having been finalized.
  
  Solution:
  
  Review Existing Costings: Check the existing cost estimates for the project. You can do this by navigating to the relevant transaction (e.g., CJ20N for project management) and reviewing the cost planning data.
  Adjust Project Status: If the project is in a status that prevents changes, you may need to change the status to allow for cost planning. This might involve unlocking the project or changing its status to a more permissive one.
  Delete or Adjust Existing Costings: If necessary, you can delete or adjust the existing costings. This can typically be done through the transaction code CJ02 (Change Project) or CJ20N (Project Builder). However, be cautious with this approach, as it may have implications for financial reporting and project tracking.
  Consult Documentation: Refer to SAP documentation or your organization's guidelines for handling cost planning in projects. There may be specific procedures in place for your organization.
  Contact Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or a consultant who specializes in SAP PS/CO modules for further assistance.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CJ20N (Project Builder), CJ02 (Change Project), and CJI3 (Project Actual Line Items) to navigate and manage project costings effectively.
  SAP Notes: Check for any SAP Notes related to this error message, as they may provide additional insights or patches that could resolve the issue.
  User Authorizations: Ensure that you have the necessary authorizations to make changes to project costings, as lack of permissions can also lead to errors.
  
  By following these steps, you should be able to address the KPN078 error and proceed with your project cost planning activities.
