• What is the cause and solution for SAP error message CK771 - Future standard cost estimate is locked ?

  The SAP error message CK771, which states "Future standard cost estimate is locked," typically occurs when there is an attempt to change or create a standard cost estimate for a future period that is currently locked in the system. This can happen for various reasons, such as:
  Causes:
  
  Locked Period: The period for which you are trying to create or change the cost estimate is locked in the controlling area. This is often done to prevent changes after a certain point in time.
  Cost Estimate Already Exists: A cost estimate for the future period may already exist, and the system does not allow modifications to it.
  Authorization Issues: The user may not have the necessary authorizations to create or modify cost estimates for the specified period.
  Configuration Settings: Certain configuration settings in the controlling module may restrict changes to future cost estimates.
  
  Solutions:
  
  Unlock the Period: If you have the necessary authorizations, you can unlock the period in the controlling area. This is typically done through transaction code OB52 (for financial periods) or through the appropriate configuration settings in the controlling module.
  Check Existing Cost Estimates: Verify if a cost estimate already exists for the future period. If it does, you may need to adjust or delete the existing estimate before creating a new one.
  Review Authorizations: Ensure that the user attempting to create or modify the cost estimate has the appropriate authorizations. This may involve checking user roles and permissions in the SAP system.
  Consult Configuration Settings: Review the configuration settings related to cost estimates in the controlling module. This may involve consulting with your SAP configuration team or reviewing documentation to understand any restrictions in place.
  Use Transaction CK11N: If you are trying to create a new cost estimate, use transaction CK11N to create a new standard cost estimate. Ensure that you are not trying to modify an existing locked estimate.

  SAP Notes: Check for any SAP Notes related to error CK771 for specific patches or updates that may address the issue.
  Documentation: Review SAP documentation on cost accounting and controlling to understand the implications of locking periods and how to manage cost estimates effectively.
