• What is the cause and solution for SAP error message WRF_APC580 - Calculation is not possible ?

  The SAP error message WRF_APC580: Calculation is not possible typically occurs in the context of APC (Activity-Based Costing) or Product Costing processes, especially when working with costing runs or cost estimates in SAP Controlling (CO) or Product Cost Planning (CO-PC).
  
  Cause of the Error
  The error WRF_APC580 Calculation is not possible generally indicates that the system cannot perform the costing calculation due to one or more of the following reasons:
  
  
  Missing or Incomplete Master Data:
  
  The cost component structure or cost element structure is not properly maintained.
  The routing or bill of materials (BOM) is incomplete or missing.
  Work center or activity type data required for calculation is missing or incorrectly maintained.
  
  
  
  Incorrect or Missing Costing Variant Settings:
  
  The costing variant used for the calculation is not properly configured.
  Parameters such as valuation variant, costing type, or date settings are incorrect or inconsistent.
  
  
  
  Inconsistent or Missing Price Data:
  
  Prices for raw materials, activities, or overheads are missing or not maintained.
  Price determination for certain cost elements fails.
  
  
  
  Technical or Configuration Issues:
  
  The system cannot find a valid costing version or costing run.
  The calculation sequence or formula in the costing sheet or overhead calculation is incorrect.
  Authorization issues or system inconsistencies.
  
  
  
  
  Solution / How to Resolve
  To resolve the WRF_APC580 error, follow these steps:
  
  
  Check Master Data:
  
  Verify that the BOM and routing for the material are complete and valid for the costing date.
  Ensure that work centers and activity types are correctly maintained and assigned.
  Confirm that cost component and cost element structures are properly defined.
  
  
  
  Review Costing Variant and Parameters:
  
  Check the costing variant settings in transaction CK40N or CK11N.
  Ensure the valuation variant, costing type, and date parameters are consistent and valid.
  Validate that the costing variant includes all necessary costing sheets and overhead keys.
  
  
  
  Verify Price Data:
  
  Check if prices for all components and activities are maintained in the system.
  Use transaction CKM3 or MR21 to verify material prices.
  Confirm activity prices in controlling are maintained (transaction KP26).
  
  
  
  Run Costing in Debug or Trace Mode:
  
  Use SAP standard tools to trace the costing run and identify where the calculation fails.
  Check application logs (transaction SLG1) for detailed error messages.
  
  
  
  Check Authorizations and System Consistency:
  
  Ensure the user has the necessary authorizations to perform costing.
  Run consistency checks for master data and costing runs.
  
  
  
  Consult SAP Notes and Documentation:
  
  Search for relevant SAP Notes on the SAP Support Portal using the error message or related keywords.
  Sometimes, specific patches or corrections are required.
