• What is the cause and solution for SAP error message WRF_APC675 - No automatic calculation, use fixing scheme and calculation button ?

  Certainly! Here's a detailed explanation for the SAP error message WRF_APC675: No automatic calculation, use fixing scheme and calculation button:
  
  Error Message:
  WRF_APC675 - No automatic calculation, use fixing scheme and calculation button
  
  Cause:
  This error occurs in the SAP Product Costing (CO-PC) or Product Cost Planning module, specifically during the costing run or cost estimate calculation process.
  
  The system is unable to perform an automatic calculation of the cost estimate.
  This typically happens when the costing variant or costing version is set up in a way that does not allow automatic calculation.
  It may also occur if the fixing scheme (a method to fix or lock certain cost components or quantities) is required but not applied.
  The system expects the user to manually trigger the calculation using the calculation button or to use a fixing scheme to control the calculation process.
  
  
  When does it occur?
  
  During cost estimate calculation for a material.
  When using costing variants that require manual intervention.
  When the system settings or user inputs indicate that automatic calculation is not allowed or not possible.
  When the fixing scheme is mandatory but missing or not applied.
  
  
  Solution:
  
  
  Use the Fixing Scheme:
  
  Check if a fixing scheme is required for the costing variant or costing version you are using.
  Apply the appropriate fixing scheme to fix certain cost components or quantities.
  This can be done in the costing run or cost estimate transaction by selecting the fixing scheme.
  
  
  
  Manual Calculation:
  
  Instead of relying on automatic calculation, use the calculation button (usually available in the cost estimate transaction screen) to manually trigger the calculation.
  This allows the system to perform the calculation step-by-step as per the fixing scheme or user inputs.
  
  
  
  Check Costing Variant Settings:
  
  Review the costing variant configuration in transaction OKKN or OKTZ.
  Ensure that the settings allow automatic calculation if that is desired.
  If automatic calculation is not supported or intended, inform users to use manual calculation.
  
  
  
  Review User Authorization and Process:
  
  Sometimes, the error can occur if the user does not have the authorization to perform automatic calculation.
  Ensure the user has the necessary permissions.
  
  
  
  Check for Customizing or User Exits:
  
  If there are custom enhancements or user exits in the costing process, verify that they do not prevent automatic calculation.
  
  
  
  
  Additional Information:
  
  
  Fixing Scheme:
  
  A fixing scheme is used in product costing to lock or fix certain cost components or quantities during cost estimate calculation. This is useful when you want to control which parts of the cost estimate are recalculated and which remain fixed.
  
  
  Costing Variant:
  
  The costing variant controls how the cost estimate is calculated, including whether it is automatic or manual, which price control is used, and which valuation variant is applied.
  
  
  Transactions to Check:
  
  CK11N - Create Cost Estimate
  CK40N - Costing Run
  OKKN - Define Costing Variants
  OKTZ - Define Costing Versions
