• What is the cause and solution for SAP error message CK900 - Material &1 in plant &2 already has a marked standard cost estimate ?

  The SAP error message CK900 indicates that a material in a specific plant already has a marked standard cost estimate. This typically occurs when you attempt to create or change a cost estimate for a material that already has a valid standard cost estimate marked for use.
  Cause:
  
  Existing Marked Standard Cost Estimate: The material already has a standard cost estimate that has been marked as active. This means that the system does not allow you to create a new cost estimate until the existing one is unmarked or changed.
  Cost Estimate Status: The cost estimate might be in a status that prevents further changes, such as being locked or finalized.
  
  Solution:
  
  
  Check Existing Cost Estimates:
  
  Go to the transaction code CK13N (Display Material Cost Estimate) to view the existing cost estimates for the material in question.
  Identify if there is a marked standard cost estimate.
  
  
  
  Unmark the Existing Cost Estimate:
  
  If you need to create a new cost estimate, you can unmark the existing one. This can be done using transaction code CK24 (Mark/Unmark Cost Estimates).
  Select the cost estimate you want to unmark and proceed with the unmarking process.
  
  
  
  Create a New Cost Estimate:
  
  After unmarking the existing cost estimate, you can create a new cost estimate using transaction code CK40N (Create Cost Estimate with Quantity Structure) or CK11N (Create Cost Estimate).
  
  
  
  Review Costing Variants:
  
  Ensure that the costing variant you are using allows for the creation of new cost estimates. Check the settings in transaction code OKKN (Define Costing Variants).
  
  
  
  Consult Documentation:
  
  If you are unsure about the implications of unmarking a cost estimate, consult your organization's documentation or speak with a financial controller or cost accountant.
  
  
  
  Related Information:
  
  Costing Variants: Understand the costing variant settings, as they control how cost estimates are created and processed.
  Costing Sheets: Review the costing sheets associated with the material, as they may affect how costs are calculated.
  Material Master Data: Ensure that the material master data is correctly set up, as incorrect settings can lead to issues with cost estimates.
  Authorization: Ensure you have the necessary authorizations to make changes to cost estimates.
  
  By following these steps, you should be able to resolve the CK900 error and proceed with your cost estimation tasks in SAP.
