• What is the cause and solution for SAP error message CK120 - Parameter error: T_KOMK1 is empty ?

  The SAP error message CK120, which states "Parameter error: T_KOMK1 is empty," typically occurs in the context of pricing and cost calculations within the SAP system, particularly in the Controlling (CO) and Sales and Distribution (SD) modules. This error indicates that the system is expecting certain pricing condition data to be present, but it is not available, leading to a failure in processing.
  Cause:
  
  Missing Data: The most common cause of this error is that the pricing condition records are not maintained properly. This could be due to missing entries in the condition tables or missing master data (like material master, customer master, etc.).
  Incorrect Configuration: There may be issues with the configuration of pricing procedures or condition types that lead to the system not being able to retrieve the necessary data.
  Custom Code Issues: If there are custom enhancements or modifications in the pricing logic, they might not be handling certain scenarios correctly, leading to this error.
  Transaction Context: The error may also arise if the transaction context does not have the necessary data loaded into the memory, which can happen in certain transaction flows.
  
  Solution:
  
  Check Condition Records: Verify that the necessary condition records are maintained for the relevant pricing conditions. You can do this using transaction codes like VK11 (Create Condition) or VK12 (Change Condition).
  Review Pricing Procedure: Ensure that the pricing procedure assigned to the sales document or material is correctly configured and that all required condition types are included.
  Check Master Data: Ensure that the relevant master data (customer, material, etc.) is complete and correctly set up. Missing or incorrect master data can lead to this error.
  Debugging: If the issue persists, consider debugging the pricing logic to identify where the data is being lost or not populated. This may require the assistance of a developer or SAP consultant.
  Consult Documentation: Review SAP notes and documentation related to the specific version of SAP you are using, as there may be known issues or patches available.
