• What is the cause and solution for SAP error message CK635 - Saving new cost estimate overwrites marked cost estimate ?

  The SAP error message CK635, which states "Saving new cost estimate overwrites marked cost estimate," typically occurs in the context of cost estimating in SAP's Controlling (CO) module, particularly when dealing with cost estimates for materials or products.
  Cause:
  This error arises when you attempt to save a new cost estimate that would overwrite an existing cost estimate that has been marked for a specific purpose (e.g., marked for future use, marked as a standard cost estimate, etc.). The system is designed to prevent unintentional overwriting of important cost estimates that may be in use for various financial reporting or planning purposes.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Cost Estimates: Review the existing cost estimates for the material or product in question. You can do this using transaction codes like CK13N (Display Material Cost Estimate) to see the current cost estimates and their statuses.
  
  
  Unmark the Existing Cost Estimate: If the existing cost estimate is no longer needed or can be modified, you may consider unmarking it. This can be done using transaction CK24 (Mark/Unmark Cost Estimates). However, be cautious with this step, as it may affect other processes relying on that cost estimate.
  
  
  Use a Different Version: If you need to keep the existing cost estimate intact, consider saving the new cost estimate under a different version or as a different type (e.g., a temporary cost estimate). This way, you can maintain both estimates without conflict.
  
  
  Consult with Stakeholders: If the cost estimate is critical for financial reporting or planning, consult with relevant stakeholders (e.g., finance team, production planners) to determine the best course of action.
  
  
  Check Authorization: Ensure that you have the necessary authorizations to modify or overwrite cost estimates. Lack of proper authorization can sometimes lead to unexpected errors.
  
  
  Related Information:
  
  Cost Estimate Types: Understand the different types of cost estimates in SAP (e.g., standard cost estimates, planned cost estimates) and their implications on financial reporting.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CK11N (Create Cost Estimate), CK13N (Display Cost Estimate), CK24 (Mark/Unmark Cost Estimates), and CK40N (Cost Estimate for Material).
  Documentation: Refer to SAP documentation or help files for detailed information on cost estimating processes and best practices.
  
  By following these steps, you should be able to address the CK635 error and proceed with your cost estimating tasks in SAP.
