• What is the cause and solution for SAP error message M8155 - Standard cost estimate exists in period & & ?

  The SAP error message M8155, which states "Standard cost estimate exists in period & &," typically occurs when you attempt to perform a transaction that requires a standard cost estimate, but there is already a valid standard cost estimate for the material in the specified period. This can happen in various scenarios, such as during inventory valuation, material movements, or when trying to change the cost estimate.
  Cause:
  
  Existing Standard Cost Estimate: The primary cause of this error is that a standard cost estimate for the material already exists for the specified period. SAP does not allow changes to the cost estimate if it is already in use for that period.
  Period Locking: The period in which you are trying to make changes may be locked for posting, which can also lead to this error.
  Costing Run: If a costing run has been executed and a standard cost estimate has been generated, it will prevent further changes until the period is closed or the estimate is adjusted.
  
  Solution:
  
  Check Existing Cost Estimates: Use transaction code CK13N (Display Material Cost Estimate) to check if a standard cost estimate exists for the material in the specified period. If it does, you may need to adjust or release it.
  Change the Period: If you are trying to create or change a cost estimate, ensure that you are working in a period where no existing estimates are present. You may need to move to a different period or wait until the current period is closed.
  Adjust Cost Estimate: If you need to update the cost estimate, you may need to create a new cost estimate for a future period or adjust the existing one if it is permissible.
  Consult with Finance: If you are unsure about the implications of changing cost estimates, consult with your finance or controlling team to ensure compliance with accounting practices.
  Unlock Period: If the period is locked for posting, you may need to unlock it, but this should be done with caution and typically requires authorization.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CK11N (Create Material Cost Estimate), CK40N (Change Material Cost Estimate), and CK13N (Display Material Cost Estimate).
  Costing Variants: Understand the costing variants and their settings, as they can affect how cost estimates are created and managed.
  Material Master Data: Ensure that the material master data is correctly maintained, as incorrect settings can lead to issues with cost estimates.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or solutions related to this error message.
  
  By following these steps, you should be able to resolve the M8155 error and proceed with your cost estimation tasks in SAP.
